[RESOLVED] Read in an Integer?
Hi, I am having trouble when I read in an integer from the keyboard and I try to display it to the screen back as the same integer. It pops out as an ASCII character. Am I doing this wrong or is there a way to read it as an integer and not a character, or do I need to convert it back? This program is using C calls. Thanks
