return is a reserved word in C. Call your variable something else.

[GWatt]

First off,
I didn't mention anything at first as it was only a few lines of code

Second, return is reserved for the purpose of exiting a function. If you specify a value with return that value can be used from wherever you called your function.

int add(int a, int B)/> {
    return a + b;
}

int main() {
    int sum = add(5, 7);
    printf("5 + 7 = %d\n", sum);

    return 0;
}

return is not a variable. You cannot assign a value to it, retrieve a value from it, get its address, or anything else you would do with a variable. Using return like you have in your arithmetic functions (add, sub, product, divide) is correct but that usage does not assign the value of whatever expression you use with return to return. It's also not a function. You don't need the parenthesis around the expression you return, but it does nothing wrong either.

Also, it looks like

if (return == 0) {
    printf("INCORRECT");
}
else {
    printf ("CORRECT");
}

is outside of a function which is wrong and will not compile either. You don't need to check the return value of your main function, if that's what you're trying to do.

*EDIT* Damn you GWatt; beat me to it.

Use code tags!

[ code] Insert code here [/code ] (without spaces between brackets)

Also NEVER call main manually it is bad!

int add(int m1,int m2,int m3,int m4,int m5)
{
return(m1+m2+m3+m4+m5);
}

int sub(int m1,int m2,int m3,int m4,int m5)
{
return(m1-m2-m3-m4-m5);
}

int product(int m1,int m2,int m3,int m4,int m5)
{
return(m1*m2*m3*m4*m5);
}

int divide(int m1,int m2,int m3,int m4,int m5)
{
return(m1/m2/m3/m4/m5);
}

if (return == 0)
{printf("INCORRECT");}
else {printf ("CORRECT");} 

This makes no sense at all. You have if statements floating in the middle of no where. And you didn't even change the variable name. As was stated return is a reserved keyword.

This is the third time someone has asked you to use them. Code tags improve readability.
What you've written should work. Did you put that inside of a function or is it hanging around in the middle of nowhere? If you need to, post the entire program, but please

[CodeGrappler]

You really need to post the entire code file.

You have posted an insufficient amount of data for us to be able to properly help you.

Also stop using Turbo-C++.

It appears to be hanging out in the middle of no where. If statements must be inside a function. You need to move the if statement inside of main and also you need to define the variable "m" before you can use it. Lastly, as previously mentioned, you should not be calling main() from a function... and especially not within main().

You forgot to post in code tags

And i found this in your code

void main()

never use void main it's

int main()

Also the conio library is outdated, it's not really good to use.

Where are your code tags?????

You are trying to define a function within a function which is wrong.

void func()
{ int m;
int add(int m1,int m2,int m3,int m4,int m5)

Please study the following links: Program structure, Functions I, Functions II.
