With C++ and C, the main function must be declared as an int, and therefore must return an int. In your code, you had changed the main function to a void, returning an error. Try changing void main() to int main() and add a line at the end of your function that returns 0. int main(){ statement(s) return 0; }

main requiring a return type of int couldn't possibly be the answer could it?

It's necessary for main() function to return an integral value (0) to operating system because it checks the number to verify that the program has run successfully or not . If it returns a value 0 it has ran successfully or any other value means it contains a problem int main() { // }
