Using a Return

hatefacecore (9)
I won't post the entire code because it ranges about 200 lines. Only one part of my code is giving me trouble. I made a function that returns a different number depending on the user's input. What I want to do is have an if else in int main. For example if the return of the function is 1 then this happens. Anyways, here's the code;

Instead of this:
1
2
3
 
    StartMenu ();
    //Here is where I want the if else.
    if(return == 1)


try this:
 
 
    if (StartMenu() == 1)

or assign the value to a variable and then use that:
 
 
    int menuvalue = StartMenu();

Look at the first example: main calls a function and assigns the return value to a variable, then uses the variable.
