write a function solution that given an integer n returns a string consisting of n lowercase lettersn
Answers
Answer:
Following are the method to this question:
def solution(s):#defining a method solution
x=0#defining variable x that assign value 0
for i in s:#defining for loop to count string value in number
if(i.islower()):#defining if block that check input character is in lowercase
x=x+1#increment the value of x by 1
return x#return x
s=input("Enter string:")#defining s variable that input string value
print(solution(s))#defining print method to solution method
Output:
Enter string:Database is the colloection
22
Explanation:
In the given question some data is missing, that's why we define the answer as follows:
In the above code, a solution method is defined, which takes "s" variable as the parameter, and inside the method, an integer variable "x" is defined, that holds a value that is "0". In the next line, for loop is declared, that counts string value without space and inside the loop, if block is defined, that checks only the lowercase character and adds the value in x variable, and returns its value. Outside the method s variable is defined, that inputs the string value from the user end, and use the print method to call it and print its calculated value.The function returns a string of lowercase alphabets of length n, which is prescribed in the function. The function written in python 3 goes thus ;
import string, random
#import the string and random modules
l_case = [x for x in string.ascii_letters if x.islower()]
#use list comprehension to take a list of lower case alphabets
def n_letters(n):
#initialize a function which takes a single parameter, number of letters
lett = random.sample(l_case, n)
#take a random sample of n letters
return "".join(lett)
#use the join function to concatenate the string
print(n_letters(6))
# A sample run of the program is attached.

Explanation:
The above program first prompts the user to enter two numbers. Here the data type of two number is float in order to accept floating numbers. The switch statement contains cases which execute according to the choice of user. The choice available to user is: 1,2,3,4 and 5
If the user selects 1 then the case 1 executes which calls the method add. The method add takes two numbers as parameters, adds the two numbers and returns the result of the addition. This result is displayed on output screen. However if the result of addition is a negative number then the message: "Oops option 1 is returning the negative number that is:" is displayed on the screen along with the negative answer of that addition.
If the user selects 2 then the case 2 executes which calls the method sub. The method works same as add but instead of addition, sub method takes two numbers as parameters, subtracts them and returns the result of the subtraction.
If the user selects 3 then the case 3 executes which calls the method mul. The method mul takes two numbers as parameters, multiplies them and returns the result of the multiplication.
If the user selects 4 then the case 4 executes which calls the method div. The method div takes two numbers as parameters and checks if the denominator i.e. second number is 0. If its 0 then Division by 0 message is displayed along with result i.e. infinity. If second number is not 0 then method divides the numbers and returns the result of the division.
If the user selects 5 then the case 5 executes which calls the method average. The average method then asks the user to enter two more numbers first2 and second2 and takes the sum of all four numbers i.e. first, second, first2 and second2. Then the result of sum is divided by 4 to compute average. The method returns the average of these four numbers.

What is the output of the following code?
int main() {
int x = 10; int y = 30;
if (x < 0) {
y = 0;
}
else if (x < 10) {
y = 10;
}
else {
y = 20;
}
cout << y;
return 0;
}
Select one:
a. 0
b. 10
c. 20
d. 300
Answers
Answer:
c. 20
Explanation:
The program works as following:
x is initialized to 10
y is initialized to 30
if (x < 0) statement checks if the value of x is less than 0. This condition evaluates to false because x=10 so 10 is greater than 0. So the statement inside the body of this if condition will not execute. Hence the program control moves to the else if part:
else if (x < 10) statement checks if the value of x is less than 10. This condition evaluates to false because x=10 so x is equal to 10 and not less than 10. So the program control moves to the else part and the statement in else part executes:
else {
y = 20;
}
This statement in else part assigns the value 20 to y
Then the program control moves to the following statement:
cout << y;
This statement prints the value of y. As the else part assigns 20 to y so the output is:
20
A mobile base station (BS) in an urban environment has a power measurement of 15 µW at 175 m. If the propagation follows an inverse cube-power law (Section 3.2.2), what is a reasonable power value, in µW, to assume at a distance 0.7 km from the BS?
Answers
Answer:
The reasonable power will be "0.234 μW".
Explanation:
The given values are:
P = 15 μW
d = 175 m
As we know,
Propagation follows inverse cube power law, then
∴ [tex]Power \ \alpha \ \frac{1}{d^3}[/tex]
⇒ [tex]Power=\frac{K}{d^3}[/tex]
On substituting the estimated values, we get
⇒ [tex]15\times 10^{-6}=\frac{K}{(173)^3}[/tex]
⇒ [tex]K=15\times (175)^3\times 10^{-6}[/tex]
Now,
"P" at 0.7 km or 700 m from BS will be:
⇒ [tex]P=\frac{K}{d^3}[/tex]
⇒ [tex]P=\frac{15\times (175)^3\times 10^{-6}}{(700)^3}[/tex]
⇒ [tex]P=0.234 \ \mu W[/tex]

Define the missing member function. Use "this" to distinguish the local member from the parameter name.

void SetNumDays(int numDays);
int GetNumDays() const;
private:
int numDays;
};
// FIXME: Define SetNumDays() member function, using "this" implicit parameter.
void CablePlan::SetNumDays(int numDays) {
/* Your solution goes here */
return;
}
int CablePlan::GetNumDays() const {
return numDays;
}
int main() {
CablePlan house1Plan;
house1Plan.SetNumDays(30);
cout << house1Plan.GetNumDays() << endl;
return 0;
}
Answers
Answer:
Here is the complete member function:
void CablePlan::SetNumDays(int numDays) { //member function of class CablePlan which take numDays as parameter
this->numDays = numDays; // refers to the fields numDays of CablePlan class using this keyword
return; }
Explanation:
The complete program is:
#include <iostream> //to use input output functions
using namespace std; //to identify objects like cin cout
class CablePlan{ //class
public: //public methods of class
void SetNumDays(int numDays); //method of class CablePlan that takes numDays as parameter to set the days
int GetNumDays() const; // method of class CablePlan to get no of days
private: //private data member of class CablePlan
int numDays; //private data member of class CablePlan that holds no of days
};
// FIXME: Define SetNumDays() member function, using "this" implicit parameter.
void CablePlan::SetNumDays(int numDays) { /
this->numDays = numDays; // used to refer to numDays variable of CablePlan class using this keyword
return;}
int CablePlan::GetNumDays() const { //define member function GetNumDays
return numDays;}
int main() { //start of main function
CablePlan house1Plan; //creates object of CablePlan class
house1Plan.SetNumDays(30); //uses object to call member function of CablePlan passing value 30 to it in order to set no of days
cout << house1Plan.GetNumDays() << endl; //uses object to call member function of CablePlan to get the no of days (numDays)
return 0;}
Here this keyword is used to refer to the field i.e. numDays of CablePlan class. This distinguishes local member numDays from parameter numDays using this with -> symbol.
'this' pointer retrieves the object's numDays which is hidden by the local variable numDays . The output of this program is:
30
Answer:
this.numDays = numDays;
Explanation:
You just need one line of code. "this." to access the class member, and the "." is the member access operator.

Technicians who travel constantly and are most likely working from remote locations would require information support that is ready and available as at when needed (24/7). The following would help them access technical information easily:
Internet knowledge based system: this could be like a encyclopedia for technicians where they could easily search up information they need for their work from anywhere.
Web-based system : this can help technicians ask or search for technical information online and also communicate and give out information to other technicians.
fax and email: a ready and available email support system and fax would boost information availability to technicians
Based on the information given, the system that should be implemented should be one where the information will be stored in a database.
Also, the system will have an application that the technicians will use to login into the system. It should also be noted that the system will be divided based on the technician's roles.
In this case, the technicians will have different access that they can use to get the data from the database.
Lastly, encryption should be used to secure the data.

Options :
The domain name is registered to someone else.
Domain names must end in ".com".
You are not the legal owner of ABC Company.
Domain names must be all in lowercase.
Answer:
The domain name is registered to someone else.
Explanation: In the scenario above, ABCcompany.org represents the domain name of a particular person or establishment which provides access to the website of the owner. The domain name given to an individual or website must be distinct, that is no two different organizations or persons can use exactly the same domain name. Domain names can end with :. com, org, ng and various other and they aren't case sensitive. Therefore, the inability to register the domain name abive will likely stem from the fact that the domain name has is already registered to someone else.
The domain of a website is the name of the website. The most likely reason why the domain cannot be registered is that, it has already been registered/taken by someone else.
There are several reasons why a domain cannot be registered.
The most important reason is that:
When a domain is taken, no other person can have access to that domain until its expiry (and not renewed). So, when a domain has been taken, you will not be able to register such domain.
Another reason is that:
Insufficient funds is another reason, if the domain is not a free domain.

Would two bits be enough to assign a unique binary number to each vowel in the English language?
Answers
Answer:
Two bits would be not enough.
Four bits would be enough.
Explanation:
With two bits, only 4 unique binary numbers are available. They are:
00
01
10
11
And since there are 5 lowercase vowel letters and 5 uppercase vowel letters in the English language, making a total of 10 vowel letters, two bits will only cater for 4 of the 10 letters and as such will not be enough.
With three bits, only 8 unique binary numbers are available. They are:
000
001
010
011
100
101
110
111
Three bits will therefore only cater for 8 of the 10 letters and as such will not be enough.
With four bits however, there are 16 binary numbers available. They are:
0000
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010
1011
1100
1101
1110
1111
Four bits are more than enough to cater for all the 10 vowel letters in the English language.
PS: The number of unique binary numbers that can be found in n bits is given by;
2ⁿ
So;
If we have 3 bits, number of unique binary numbers will be
2³ = 8
If we have 6 bits, number of unique binary numbers will be
2⁶ = 64
Using bits concepts, it is found that two bits is not enough to assign a binary number to each vowel in the English language, as two bits can represent at most 4 symbols, and there are 5 vowels.

Modern car odometers can record up to a million miles driven. What happens to the odometer reading when a car drives beyond its maximum reading?
Answers
Answer:
It would go to 1000000. Explanation:Unlike old vehicle odometers that will reach 999999 and stay there(though it is very unlikely to reach that figure) new vehicle odometers have the seventh digit reading and when it passes 999999 it would clock to 1000000.
But in reality it is less likely for vehicles to reach the 999999 mark and most vehicle owners do not get to see their vehicles reach this mark as the vehicle will either be scrapped or abandoned before it gets to that million mile
Further, the ideal behind this million miles is due to the act of bad guys who tend to spin vehicle odometers to falsify their readings making it seem as though it has not gone a long mile.
The odometer reading of a modern vehicle resets to Zero, once it's maximum odometer reading is reached.
The odometer is a recording instrument in a car which is used to measure and keep a record of the total distance a car or wheeled machine such as bicycles has covered since their manufacture. The odometer is different from a speedometer which shows the current speed at which a car is moving. The odometer keeps track of distance, such that it takes the Cummulative sum of the distance covered usually in miles. The odometer resets to 0 once it's maximum value is exceeded.Learn more : https://brainly.com/question/21087757?referrer=searchResults
