Hand in one even numbered question+answer at the start of class.
9.5 Arguments of main
The main function in a program has arguments.
int main(int argc, char* argv)It gets their values from the user's command. The first is a count of the number of arguments. The second is an array of old C strings (char*). The first "argv" is the command the user typed! The "argv" is the next word the user types. and so one. Note: argc is always one more than the subscript of the last "arg". Going past this can lead to undefined behaviors and programs crashing.
