For parameter passing, call by constant reference is for the function if the value of the actual parameter isn't changed and does no copying. Group of answer choices True False

Here is the main function in a program int main () { int x = 30; //more code goes here someFunction (x) ; cout « x; return 0; } Assume the heading for someFunction is written correctly with an integer parameter named x, and that this is the body of that function: { x = x * 20; //more code goes here } What will be the output? Just enter a number. If there would be an error, enter -999

Invoking a function that takes many arguments, the order in which parameters are supplied is crucial.

IN C++

What are the assertions that describe how a function works?

Write the function prototype of the void function named G() that takes an int reference parameter and two char parameters respectively Your answer

Write a function named product that takes two int parameters and returns the product of those two integers. Here is an example: int n = product(7, 5); // n is 35 We are providing a test framework that, if you wish, you may use with a compiler to test your function. What you will submit as your answer to this problem is only the product function. Do not submit things like the #include lines or a main routine. If we take the code you write in the space below and insert it into the program, the resulting program must build without compilation errors (mere warnings are allowed). You do not need to write comments in the code; we will not look at any comments. Here is the test framework that you may copy and paste into a C++ source file. For your own testing purposes, you might add additional tests in the main routine, although you won't be turning them in, of course. #include <iostream> #include <cassert> using namespace std; // SUBMIT AS YOUR ANSWER ONLY THE CODE BETWEEN THIS…
