main() function requirements

The main() function must return int
- The return values are 0 and -1
  - 0: SUCCESS
  - -1: FAILURE (any non-zero can be used)
- C++ Core Guideline
- Main function specifications
The two forms allowed are:
- int main() { body }
- int main( int argc, char *argv[] ) { body }
