I have made an atm, but when i enter a character it crashes. How do I stop this from happening?
printf("Please select an option: ");
scanf("%d", & Option);//It will only accept numbers 1-4
That is what I'm using for the 4 options the user needs to choose from. If you choose a number that's not 1-4 it gives an error. But a character will crash it.
RTM,
man page scanf section 3
Have you learnt if... [else] ?
Yeah, it fully works with an Int, but I just need to get it to stop crashing if anything other than an Int is entered. I'll look at that page now. Thanks
You could use fgets() + sscanf()/strtol.
again don't forget to RTM!
use %s then throw the var into atoi(). you won't crash and still it'll be numerical-only.
