Please hurry!

This is the prompt for my C++ program. I have already written it but I believe did something wrong with my declared integers. But Im not sure. Please look at my prompt and rewrite my program as is but fixing my mistake. Thank you

Exercise 1: The purpose of this lab is to reinforce writing and calling functions in C++ Specifically, you need to construct a function that has 2 integer arguments and returns whether the first argument is a multiple of the second. The "main" function needs to test this function by using test cases which represent all possible behaviors of the function. You need to use good design principles including the preconditions and postconditions used by the author. 1 //Precondition: b does not equal 0 2 //Postcondition: If a multiple of b, will return true 4 include 5 using namespace std: 6 bool multiple (int a,int b) return a % b == 0; 10 int main) ( 11 int a, b; 12 cout b 16 while (b 17 18 19 20 if (multiple (a, b))t 21 22) 23 else f 24 25 26 1 27 cout > b cout
