A while loop is used to repeatedly execute a block of code as long as a specified condition is true. In the context of the given options:

Option A could use a simple if-else statement to compare two numbers and print the larger one.

Option B is a classic example of a use case for a while loop. The loop can run until the correct password is entered or the maximum number of attempts is reached.

Option C could be accomplished with a single if statement to check if the number is a multiple of 10.

Option D can also be done with an if-else statement to check the properties of the number.

Therefore, the task that is best suited for a while loop is Option B, where the user is asked to enter a password repeatedly until a correct password is entered or a certain number of incorrect attempts have been made. This requires the program to loop through the password prompt and check the conditions after each input, which is what while loops are designed for.

A grade point average (GPA) is a numerical value that typically includes decimal places (e.g., 3.75). According to foundational programming principles, it should be declared as a variable if it may change (e.g., as grades are updated) and as a floating-point type to accommodate decimals.

Option A: "Variable float gpa." This is correct. GPA requires a floating-point type (float) to handle decimal values, and since it may change over the term, it should be a variable, not a constant. For example, in C: float gpa = 3.5;.

Option B: "Constant float gpa." This is incorrect. A constant (const in C) cannot be modified after initialization, but GPA may change as new grades are added.

Option C: "Variable int gpa." This is incorrect. An integer (int) cannot store decimal values, which are common in GPAs (e.g., 3.2).

Option D: "Constant int gpa." This is incorrect. GPA requires a float for decimals and a variable for mutability, making both const and int unsuitable.

Comprehensive and Detailed Explanation From Exact Extract:

A function definition specifies how a function operates, including its name, parameters (inputs), return type or values (outputs), and the statements it executes. According to foundational programming principles, a function definition is distinct from a function call or its usage.

Option A: "The function’s name, inputs, outputs, and statements." This is correct. A function definition includes:

Name (e.g., myFunction).

Inputs (parameters, e.g., int x, int y).

Outputs (return type or value, e.g., int or return x + y).

Statements (body, e.g., { return x + y; } in C).For example, in Python: def add(x, y): return x + y.

Option B: "A list of all other functions that call the function." This is incorrect. A function definition does not track or include its callers; it defines the function’s behavior.

Option C: "An invocation of a function’s name." This is incorrect. An invocation (call) is when the function is used (e.g., add(2, 3)), not its definition.

Option D: "The function’s argument values." This is incorrect. Argument values are provided during a function call, not in the definition, which specifies parameters (placeholders).
