Can't figure out why this won't run.

甚至不编译：你正在使用未定义的符号是和没有（您还使用了需要字符串的整数变量）。 />


尝试：

It even don't compile: you are using undefined symbols yes and no (you are also using an integer variable where a string is required).

Try:

#include <iostream>
#include <string>
using namespace std;
 
int main ()
{
  string answer;
 
  cout << "Am I the best person on this earth?\n";
  cout << "Please enter 'yes' or 'no'.\n";
  cin >> answer;
 
  if (answer == "yes")
  {
    cout << "You are correct, heaven welcomes you!\n";
  }
  else if (answer == "no")
  {
    cout << "You are incorrect, the devil will eat your soul!\n";
  }
  else
  {
    cout << "Please answer either 'yes' or 'no'.";
  }
}

make变量：

make variables:

char yes = 'y';
char no = 'n';

试试这个

try this

int x;

cout<<"Am I the best person on this earth?\n";
cout<<"Please enter 1.yes or 0.no.\n";
cin>>x;

if (x == 1)
{

    cout<<"You are correct, heaven welcomes you!\n";

}

else if (x == 0)
{
    cout<<"You are incorrect, the devil will eat your soul!\n";

}
else
{

    cout<<"Please answer the queston";

}
