I am working on a project, where you answer a char, and if it is not one of the 4 answers, it tells you to try again. If it is not the correct one of the 4, it stops running. Here is a snippit.

#include <stdio.h>
#include <stdbool.h>
bool switchCheck = true;
char answer;

        printf("A. English\nB. French\nC. Spanish\nD. German\n");
      do{
        scanf("%c\n", &answer);
        switch (answer){
          case 'C':
            printf("Very nice ");
            break;
          case 'B':
          case 'A':
          case 'D':
            printf("Sorry! Incorrect. Code Ends\n");
            switchCheck =false;
            break;
          default:
            printf("Try Again\n");
        }
      }while(switchCheck==true);
     

For some reason, when I input A, B, or D, it first prints the result for default, and if I do it again immediately afterward, it gives me the right input. Any help?

Thanks!
