gets problem, for me

It has to be a very simple explanation, but I do not see it. In the program below, I expect, when I enter "quit", that it will break out of the while loop and the program ends. But, it never breaks out of the loop, what am I missing here?

Use !strcmp(buffer, "quit") instead of buffer == "quit". strcmp will compare the contents of two strings and return zero if they're equal. buffer == "quit" is comparing the address of buffer with the address of "quit", and they will never be equal since they are stored at different addresses.
