Why int main() not void main()

Answer 1

so the main function can return a value to end the program, 0 is normal termination, any other is abnormal.

Answer 2

Int main() is just a new standard, because it's thought it's best for every function to return a value. There's not much difference and you just look cooler if you follow the standard and use int instead of a void.

Answer 3

you can use void also but without return
