Handling User Input
I'm writing a small program in which a user is to input different data about themselves and then a funny quote pops up. My problem is that, for some question I want the person to enter a number and at other times words. My program works fine except when a person enters a string when I am expecting a number like an int. Is there some way that I can check the type of data that was inputted by the user before the computer tries to store the data in the int pointer.
you could read each char that the user inputs and then test for values (from '0' - '9', etc..). don't forget the value of 0 is different form the value of '0'. one is a char, the other an int.
Read all data into a char array, then convert the ones you want to an int with strtol() or atoi() or something similar
Use fgets() to do the reading too, not scanf().
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Thanx for the help!!!
