in the code segment below, mylist is an arraylist of integers. the code segment is intended to remove all elements with the value 0 from mylist. int j
Here's an example code segment in Java to remove all elements with the value 0 from an 'ArrayList' of integers called 'myList':
ArrayList<Integer> myList = new ArrayList<>(Arrays.asList(0, 1, 2, 0, 3, 0));
for (int j = 0; j < myList.size(); j++) {
if (myList.get(j) == 0) {
myList.remove(j);
j--;
}
}
In this example, the code uses a 'for' loop to iterate through the elements of the 'ArrayList'. For each iteration, it checks if the value of the current element is 0 using an 'if' statement. If the value is 0, the code removes the element using the 'remove' method and decrements ' j ' by 1 to prevent skipping over the next element. This process continues until all elements with the value 0 have been removed from the 'ArrayList'.

difference between formal planning and informal planning
Answer:
Formal planning is an articulated, written form of planning that states particular objectives and methods. Informal planning is closer to the reality of day-to-day execution.
Explanation:
In this exercise, define the type Student using a struct declaration. Your Student type must have three data members: first_name, last_name, and uin typed std::string, std::string, unsigned int respectively. Note: until you have correctly defined the data members for Student, your program will not compile with our test suite. Therefore, we encourage you to use driver.cc +the "Run" button for testing.
struct Student {
std::string first_name;
std::string last_name;
unsigned int uin;
};
What is the purpose of the struct declaration in this code?The struct declaration in the code creates a user-defined data type called Student. A struct is a composite data type in C++ that groups together variables of different data types under a single name. The purpose of the struct declaration is to define the structure of the Student type, which includes its data members. In this case, the Student type has three data members: first_name of type std::string, last_name of type std::string, and uin of type unsigned int. This struct declaration allows the programmer to create instances of the Student type in the code and to store data in the form of Student objects.

A program that prints out all six permutations of the ordering of the three lines, declaring a named constant for each line and write an output statement for each permutation. Appropriate comments are included in the code, choosing meaningful identifiers, and use indentation;
Here's an example of how you could write the program in Python:
# Named constants for each line
LINE1 = "First line"
LINE2 = "Second line"
LINE3 = "Third line"
# Function to generate all permutations
def permute(data, i, length):
if i == length:
print(data)
else:
for j in range(i, length):
# Swap the ith and jth elements
data[i], data[j] = data[j], data[i]
permute(data, i + 1, length)
data[i], data[j] = data[j], data[i]
# Call the permutation function with the initial data
permute([LINE1, LINE2, LINE3], 0, 3)
This program generates all six possible permutations of the three lines and prints each one. The permute function uses recursion to generate the permutations. The function generates the permutations by swapping elements in the data array and calling itself with the next index. The base case of the recursion is when the index i is equal to the length of the data, at which point the current permutation is printed.

Draw the hierarchy chart and design the logic for a program that calculates service charges for Hazel's Housecleaning service. The program contains housekeeping, detail loop, and end-of-job modules. The main program declares any needed global variables and constants and calls the other modules. The housekeeping module displays a prompt for and accepts a customer's last name. While the user does not enter ZZZZ for the name, the detail loop accepts the number of bathrooms and the number of other rooms to be cleaned. The service charge is computed as $40 plus $15 for each bathroom and $10 for each of the other rooms. The detail loop also displays the service charge and then prompts the user for the next customer's name. The end-of-job module, which executes after the user enters the sentinel value for the name, displays a message that indicates the program is complete.

Which of the following best describes the syntax for C structure definitions?Declaration. In general, a C struct declaration would look like this: struct tag name has two types of members: member1 and member2. You can declare as many members as you like, but the compiler needs to be aware of the size of the overall structure.
How do we determine a structure's size in C?The sizeof() operator in the C programming language is used to determine the size of structures, variables, pointers, and data types. Data types may be predefined or user-defined. We can easily calculate the size of the structure and send it as a parameter by using the sizeof() function.
