Help with C Programming (while loop)

Hello, I am fairly new to programming and need some help with the while loop.

Here is the part that I am having trouble with.

Code:

#include <stdio.h>

int main ( ) {
   int veh;


   printf("\nDo you have a car? (1:Yes, 2:No):  ");
   scanf("%d", &veh);
   while (veh < 1 || veh > 2) {
      printf("Please select 1 for Yes or 2 for No: ");
      scanf("%d", &veh);
   }
return 0;
}

The problem is is that when I type in a letter instead of a number, it displays a wall of "Please select 1 for Yes or 2 for No: ". Is there a way to fix this?

Thanks

reading input is a common beginners problem, see FAQ: How do I get a number from the user (C)
