我有下面的代码，它应该与用户交互，了解他想要做什么。

int input;
printf("Would you like to update the name of the student?\n");
printf("Enter Y(yes) or N(no)\n");
input = getchar();

if (input == 'Y' || input == 'y') {
  printf("Please enter the updated name\n");
  scanf("%s", tmpSt->name);
}

printf("Would you like to update the student's ID?\n");
printf("Enter Y(yes) or N(no)\n");
input = getchar();

但执行时它不会停止获取第一个输入。

Would you like to update the name of the student?
Enter Y(yes) or N(no)
Would you like to update the student's ID?
Enter Y(yes) or N(no)

它应该得到名称的答案，但它直接转到 …
