Thread: scanf in a loop

the first iteration of the loop works fine. then, it comes back around and asks the user to enter in a command but does not implement scanf(). can someone pls tell me how to fix this?

Code:

loop:
       
        
printf("enter command:");
scanf("%c",&x)

switch(x){
          case 'o':
               printf("open");
               goto loop;
          case 'b':
               printf("boost");
              goto loop;
          case 'q':
               printf("quit");  
             goto loop;
}
