i have use the function readfile() and put the data into a char buff[256],
but i found that there are values in buff[0] to buff[255] while it is different from what we did normally,
example:
char buff[6] ="hello";
cout << buff;
for the code above, if you define buff[6] = "hello?", it will have error right? why cant i define buff[6] to "hello?"
how to explain this? thank you
