How to use the return value of a function with parameters inside another function

Question

All these functions are outside the int main():

int func1(int x) {

    int v1 = 6 * x;
    return v1; // the input argument will be 2, so v1 = 12
}

int func2()         


        

Answer 1

Should be:

int func2(){
    int v2 = func1(2) / 4; // It's suppose to be 12 / 4
    return v2;
}

Whenever you call a function, you have to pass the parameters it requires.

You get "too few arguments" because you're not passing the right amount of arguments!
