Give an example from your own idea, of a program that use a void function (does not return avalue), based on your understanding. (You must include a main function)
Assume that the declarations for two functions look as follows: int Function1(double x); 2.void Function2(double x); Give some sample code that would show how each function could be used.
For this question you will design and implement a function that takes 5 arguments and produces 5 return values. This question is internally recognized as variant 0371. The 5 arguments must be of types int, int, bool, bool, and char (in that order), and they must be stored in parameter variables 'ham', 'bar', 'xyz', 'gzk', and 'foo', respectively. As a clarifying example, the second parameter - 'bar' - will be of type int. The function you create must perform the operations list below, in the specified order and exactly as they are described here. You are NOT permitted to simplify the operations. 1. create a new variable named 'ukr' that stores the result of increasing the 'ham' parameter by 42 2. if the conjunction of the 'xyz' parameter and the 'gzk' parameter has a value of True, multiply the value of the 'ham' parameter by a value of 29 and store the result back in 'ham' 3. negate the value of the 'xyz' parameter and store the result back in 'xyz' 4. decrease the value of the 'ham'…

Consider the following function definition: void too2(int a[ ], int howMany) { for (int index = 0; index < howMany; index++) a[index] = 2; } Which of the following are acceptable function calls? int myArray[29]; too2(myArray, 29); too2(myArray, 10); too2(myArray, 55); "Hey too2. Please, come over here." int yourArray[100]; too2(yourArray, 100); too2(myArray[3], 29);
Write a function to divide variable ‘a’ with ‘b’. Store the result in a separate variable andreturn it from the function. Practice default parameters by calling your function with 1 argumentand with 2 arguments. Use the concept of function prototyping for this question. The signature offunction is as follows: int divide (int a, int b=2)
Consider the following function call: draw_circle('red', 3) What is the function name and what is the first argument passed to the function? a. The function name is draw_circle and the first argument is 3. b. You need to see the function definition to determine the function name and arguments. c. The function name is draw_circle, but you need to see the function definition to determine the arguments. d. The function name is draw_circle and the first argument is 'red'. e. The first argument is 'red', but you need to see the function definition to determine the function name.
