What is the return value of a function that doesn't specify a return statement or simply has an empty return statement?

In C programming, if the return type of a function is Void how can you implement assert statements?  For example, Void ceasar(int n, char*x); //if char = c and n = 3 output == f  how do i use assert statements as this does not work assert (caesar(3,c)==f);

2. Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: None

Please tell me where I get wrong.

Consider the function definition below. Assume x = 5, y = 3 and j = 8 as the function starts. Which variables will change after the function finishes? void findout (int &x, int y, int &j) { for (int i = 1; i 5) { x = 2*x - 3*y; y = 4 + 3 x; } else { Oi y = 2*x - 3; x = 4 + 3% y; } } // end of for loop x and y y All three since the first and last are references. x and j

Functions like print which perform an action but don’t return a value are called: Select one: a. recursive functions b. built-in functions c. simple functions d. utility functions e. void functions
