Hello everyone.
Right, it's a simple setup for my program, it reads in a number (as an int) and then does something with it. But, as everyones probably noticed if you type in a character the program 'crashes'. I have the following code:
Code:
#include <stdio.h>
void main()
{
int temp;
printf ("Input your number: ");
while (scanf("%d", &temp) != 1)
{
while (getchar() != '\n');
printf ("Try again: ");
}
printf ("You entered %d\n", temp);
}
but I don't understand what the return value from scanf and the new line character have to do with checking for a letter! Is there an easier way of doing this? (I usually use fgets to get an input). Any help with this would be greatly appreciated.
Cheers,
Chris.
