What is a situation where it makes a difference whether you leave main() blank vs if you put int argc, char *argv[] there?
A lot of times in programs I see
int main(int argc, char *argv[])
but then I put them in my IDE with just
int main() and they work fine. What is the point?
int main(int argc, char *argv[])
but then I put them in my IDE with just
int main() and they work fine. What is the point?
The former,
int main(int argc, char *argv[]) is used when your program is using command line arguments. If you're not planning on using them, no need to include the two arguments.
