Can someone please explain the meaning of these return 1 vs return 0 vs break. I know 1 generally means true and 0 generally means false but how would they effect a return statement? Also when would you wanna use a return statement instead of a break statement and vice versa?

return x; will return the value x to the calling routine. If you called the function with rt = func(); rt will contain whatever x was. break; will immediately exit a loop even though the loop is not finished.

for (i=0; i<10; i++)
{
    --stuff--
    if (i == 7) break;
    --more stuff--
}

This loop will exit when i = 7. It won't run until i >= 10. And --more stuff-- will not be executed either.

You realy should google C functions and C control statements....You'll find the answers in these queries...

When I put "return 1" in a few of my programs it stopped execution of the rest of my program.

Nothing useful in relationship to my question. I checked the first 20 links with no luck.

Returning from a generic function, or returning from main? Returning from main means your program is "done".

A couple of while and for loops.

You did not answer Dave's question. Although we can surmise from your answer it's from main()

Could you please give me an example of returning from a function please?

ans = fnAdd(a, b);
printf("%d + %d = %d \n", a, b, ans);
int fnAdd(int x, int y)
{
    return (x+y);
}
