9.18 LAB: Exact change - methods Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is:
Answer:
Explanation:
The following code is written in Java. It asks the user to enter the amount of change needed. This is done as a double since we are dealing with coins and not full dollar values alone. It then makes the necessary calculations to calculate the number of each coin needed and outputs it back to the user. A test case has been provided in the picture below with a sample output.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
int dollars = 1;
double quarters = 0.25;
double dimes = 0.10;
double nickels = 0.05;
double pennies = 0.01;
Scanner in = new Scanner(System.in);
System.out.println("Enter Change Value: ");
double change = in.nextDouble();
int numDollars, numQuarters, numDimes, numNickels, numPennies;
double newChange;
numDollars = (int) (change / dollars);
newChange = change % dollars;
numQuarters = (int) (newChange / quarters);
newChange = newChange % quarters;
numDimes = (int) (newChange / dimes);
newChange = newChange % dimes;
numNickels = (int) (newChange / nickels);
newChange = newChange % nickels + 0.001;
numPennies = (int) (newChange / pennies);
newChange = newChange % pennies;
System.out.println("Minimum Num of Coins needed: ");
if (numDollars != 1) {
System.out.println(numDollars + " Dollars");
} else {
System.out.println(numDollars + " Dollar");
}
if (numQuarters != 1) {
System.out.println(numQuarters + " Quarters");
} else {
System.out.println(numQuarters + " Quarter");
}
if (numDimes != 1) {
System.out.println(numDimes + " Dimes");
} else {
System.out.println(numDimes + " Dime");
}
if (numNickels != 1) {
System.out.println(numNickels + " Nickels");
} else {
System.out.println(numNickels + " Nickel");
}
if (numPennies != 1) {
System.out.println(numPennies + " Pennies");
} else {
System.out.println(numPennies + " Penny");
}
}
}

How many fingers do you need to type floor
Answer:
About 0-1 fingers at minimum
Explanation:
you can type with your toes/elbow as well. Any body part really.
To type the word "floor" on a regular keyboard layout, you would generally need six fingers: three on your left hand and three on your right.
Your index finger (usually used for the "F" key) on your left hand would be utilised for the letter "f." Your middle finger (which is normally used for the "D" key) would be utilised for the letter "l."
Finally, your ring finger (which is normally used for the "S" key) would be utilised for the letter "o."
Your index finger (usually used for the "J" key) on your right hand would be utilised for the letter "o." Your middle finger (which is normally used for the "K" key) would be utilised for the second letter "o."
Finally, your ring finger (which is normally used for the "L" key) would be utilised for the letter "r."
Thus, on a typical keyboard layout, you would type the word "floor" with three fingers from each hand.

what is the process by which we can control what parts of a program can acccess the members of class
Answer:
Encapsulation.
Explanation:
Information hiding involves using private fields within classes and it's a feature found in all object-oriented languages such as Java, Python, C#, Ruby etc.
In object-oriented programming language, a process known as encapsulation is used for the restrictions of the internal data of a software program from the outside code, therefore preventing an unauthorized direct access to the codes. This is achieved through the use of classes.
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.

Write a programmer defined function that compares the ASCII sum of two strings. To compute the ASCII sum, you need to compute the ASCII value of each character of the string and sum them up. You will thus need to calculate two sums, one for each string. Then, return true if the first string has a larger ASCII sum compared to the second string, otherwise return false. In your main function, prompt the user to enter two strings with a suitable message and provide the strings to the function during function call. The user may enter multiple words for either string. Then, use the Boolean data returned by the function to inform which string has the higher ASCII sum.
Answer:
The program in Python is as follows:
def ASCIIsum(str1,str2):
asciisum1 = 0; asciisum2 = 0
for chr in str1:
asciisum1 += (ord(chr) - 96)
for chr in str2:
asciisum2 += (ord(chr) - 96)
if asciisum1 > asciisum2:
return True
else:
return False
str1 = input("Enter first string: ")
str2 = input("Enter second string: ")
if ASCIIsum(str1,str2) == True:
print(str1,"has a higher ASCII value")
else:
print(str2,"has a higher ASCII value")
Explanation:
This defines the function
def ASCIIsum(str1,str2):
This initializes the ascii sum of both strings to 0
asciisum1 = 0; asciisum2 = 0
This iterates through the characters of str1 and add up the ascii values of each character
for chr in str1:
asciisum1 += (ord(chr) - 96)
This iterates through the characters of str2 and add up the ascii values of each character
for chr in str2:
asciisum2 += (ord(chr) - 96)
This returns true if the first string has a greater ascii value
if asciisum1 > asciisum2:
return True
This returns false if the second string has a greater ascii value
else:
return False
The main begins here
This gets input for first string
str1 = input("Enter first string: ")
This gets input for second string
str2 = input("Enter second string: ")
If the returned value is True
if ASCIIsum(str1,str2) == True:
Then str1 has a greater ascii value
print(str1,"has a higher ASCII value")
If otherwise
else:
Then str2 has a greater ascii value
print(str2,"has a higher ASCII value")

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray
I understand you want a function that swaps the first and last element of an array so that the first element takes the last one's value and vice versa.
Answer and Explanation:
Using Javascript programming language:
function swapArrayEnds(sortArray){
var newArray= sortArray.values();
var firstElement=newArray[0];
newArray[0]=newArray[newArray.length-1];
newArray[newArray.length-1]=firstElement;
return newArray;
}
var exampleArray=[2, 5, 6, 8];
swapArrayEnds(exampleArray);
In the function above we defined the swapArray function by passing an array parameter that is sorted by swapping its first and last element. We first get the elements of the arrayvusing the array values method. We then store the value of the first element in the variable firstElement so that we are able to retain the value and then switch the values of the first element before using the firstElement to switch value of the last element. We then return newArray and call the function.
