c++ - 标识符未被初始化

Question

在这里做学校项目遇到了问题我的程序支持用户猜测一个数字 47，如果他们猜错了，他们总共有 5 次尝试。如果仍然没有得到它，程序将退出。如果他们得到了它，将会有一条消息说需要多少次尝试才能得到答案。因此，我必须有一个标识符来表示它所花费的尝试次数。但是 C++ 说我没有初始化标识符。请帮忙

#include <iostream>
using namespace std;

int main()
{
  int intSecretNum = 47;
  int intGuess;
  int GuessNum;
  cout<< "Guess the secret number (between 0 and 100 inclusively): ";
  cin>> intGuess;
while(intSecretNum != 47, GuessNum<= 5)
{
        if( intGuess < intSecretNum)
            cout << "Your Number is smaller than the secret number";
        else if (intGuess > intSecretNum)
            cout << "Your Number is bigger than the secret number";
        GuessNum++;
        if(GuessNum>5)
            cout << "Sorry, you have used up all your quota (5 times)! The secret number is "<<intSecretNum;
            cout << "program terminated." <<endl;
}
cout<< "You have used "<<GuessNum <<" to guess te secret number which is " <<intSecretNum<<".";
cout<<"program terminated."<<endl;
return 0;
}

请帮忙=D

您忘记初始化 GuessNum:

int GuessNum = 0;

此外，while 条件中的逗号并不像您认为的那样，您的意思是 && 在 C++ 中是“and”。
