Question about int main()

Hi.
What does 'int argc, char *argv[]' inside of 'int main()' do?
And is it needed?
Thanks,
Phillip

They are used if you or other program that calls your program want to pass command line parameters to your program. If you run your program without passing any command line parameters then you can define the function simply as
int main()
{
...
}
int main()
{
...
}
