Help with integer inputsThis may have an easy solution, but I cant figure out how to do this. I am looking for the user to input an integer. The variable is defined as an integer, but when the user enters a character it still works through the code. Is there a way to verify if the user has entered an integer? I would like to possibly display an error message if they enter a character so I would like a way to recognized a character input and for it to react as i wish. Im working with c++ and the cin command for the input. Thanks for your help

You can use the functions located in ctype.h:
CPP / C++ / C Code:
Or create your own: CPP / C++ / C Code:
If the integer'll be more than 1 character long I think you'll just have to loop through the string and test each character. |
