    Question 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
