>It's not compulsory to have default at the end.
i knw but its at the end of the switch in his program.so i replied tht break is not required.
>ok..but what's the purpose of the: int argc, char *argv[] inside the () of main???
argc specifies the number of command line arguments and the array argv[] contains those arguments. In Salem's program, he is printing depending on the number of arguments given by the user.
If you don't want to worry about command-line arguments, you can declare main() like this:
orCode:int main() { return 0; }
I prefer the second.Code:int main(void) { return 0; }
