Given the following function header: float calcTotal$($float num$1,$ int type$)$

a$.$ What is the name of the function

b$.$ What type of value is returned by the function

c$.$ What types of values are passed to the function

Indicate which of the following is a function prototype, a function header, or the function call.

$1$ void showNum$($double num$)$

$2$ void showNum $($double$)$;

Write a function named calcArea that is passed a circle's radius as a float. The function should calculate the area of the circle given the formula: $A=r^2.$

A$.$ Write the function main that inputs the radius and then calls the function calcArea. Use a function prototype for the function.

B$.$ Write a displayOutput function that displays the radius and the area of the circle.

Write a while loop that will input $50$ numbers and add them up$.$

Rewrite this loop as a for loop

A program accepts two real numbers and a select code entered by the user. If the select code is $1,$ the program should add the two numbers and display the result, if the select code is $2,$ the program should subtract the two numbers and display the result, and if the select code is $3,$ the program should multiply the two numbers and display the result. If the select code is not $1,2,$ or $3,$ an error message should be displayed.
