Question

嘿，我在这里有这个程序

#include <iostream>

using namespace std;

int main()
{
  int MyNum;
  int ComNum;
  MyNum = 5;

   do {
     cout << "Enter a whole number between 1 and 10: ";
     cin >> ComNum;
     if (ComNum > MyNum) {
       cout << "Sorry that is incorrect (Hint: too high)";
     }
     if (ComNum < MyNum) {
       cout << "Sorry that is incorrect (Hint: too low)";
       cin >> ComNum;
     }
   } while(MyNum != ComNum);
   cout << "Correct"
}

而且我不知道为什么在第一个不正确的答案后它将无法继续运行，我确定我错过了一些小而愚蠢的东西（PS），这是我猜数字游戏的猜测，如果您不能从代码

Answer 1

缺少分号后，将给出错误提示：

#include <iostream>

using namespace std;

int main()
{
  int MyNum;
  int ComNum;
  MyNum = 5;

   do {
     cout << "Enter a whole number between 1 and 10: ";
     cin >> ComNum;
     if (ComNum > MyNum) {
       cout << "Sorry that is incorrect (Hint: too high)";
     }
     if (ComNum < MyNum) {
       cout << "Sorry that is incorrect (Hint: too low)";
       cin >> ComNum;
     }
   } while(MyNum != ComNum);
   cout << "Correct";
}

正如其他人所说，第二个cin >> ComNum；尽管它可以在https://www.onlinegdb.com/online_c++_compiler上使用

，但这是不必要的

Answer 2

只需在IF中删除cin >> ComNum;，然后修复编译器错误cout << "Correct";。

循环不继续无法弄清楚为什么
