如何将字母放入“interger”中C ++中的问题 [英] How do I put letters in "interger" problems in C++

问题描述

#include

 #include< iostream> 
 
 main（）{
 using namespace std; 
 cout<< 完成数学问题。 << ENDL; 
 int x; 
 int y; 
 x = 5; 
 y = 5; 
 cout<< 答案是x + y<< ENDL; 
 cout<< 答案是x * y<< ENDL; 
 cout<< 答案是x / y<< ENDL; 
 cout<< 答案是x  -  4<< ENDL; 
 cout<< 答案是x  -  2<< ENDL; 
 cout<< 答案是x / 10<< ENDL; 
} 

这对我不起作用？

解决方案

你应该尝试更换：

 cout<<  答案是 x + y<< ENDL; 
 

with

 cout<<  答案是<< x + y<< ENDL;

因为您没有阅读文档： istream的::运营商GT;> - C ++参考 [ ^ ]。

#include

#include <iostream>

main(){
    using namespace std;
    cout << "Finish the math problem." << endl;
    int x;
    int y;
    x = 5;
    y = 5;
    cout << "The answer is" x + y << endl;
    cout << "The answer is" x * y << endl;
    cout << "The answer is" x / y << endl;
    cout << "The answer is" x - 4 << endl;
    cout << "The answer is" x - 2 << endl;
    cout << "The answer is" x / 10 << endl;
}

This doesn't work for me?

解决方案

You should try to replace:

cout << "The answer is" x + y << endl;

with

cout << "The answer is" << x + y << endl;

Because you didn't read the documentation: istream::operator>> - C++ Reference[^].
