[Solved] how to write a function for numbers

by


You’re already given the function signature: int largest(), so that’s exactly how you’d write the function (exactly like int main();):

// Declares the function
int largest();
// Defines the function:
int largest()
{
    // The function MUST return an int (or something convertible) otherwise it will not compile
    return 0;
}

Or you can combine the declaration with the definition:

int largest()
{
   return 0;
}
