The following code in C accepts integers as long as data is fed into it.
#include<stdio.h>
#include<conio.h>
void main()
{
int x;
while(scanf("%d",&x)!=EOF)
{
printf("%d\n",x);
}
getche ();
}
It works fine for integer inputs but on entering any character/float input it becomes an infinite loop.Why is it so ?
If scanf failes to parse any input, it will leave the input in the buffer and return 0. As the erroneous input will never leave the buffer and you don't check for anything but EOF being returned, the loop will continue for ever.
