在C ++中收到此错误，“与'operator>>不匹配"在'std:cin.std中 [英] Getting this error in C++, "no match for 'operator>>' in 'std:cin.std

问题描述

#include <iostream>

int main()
{
    using std::cout;
    using std::endl;
    using std::cin;
    short width;
    short legnth;
    short height;
    short volume;
    volume = (legnth * width * height);

    cout << "This program will determine the volume of a cube" << endl;
    cout << "Enter the legnth of the cube: ";
    cin >> legnth >> endl;
    cout << "Enter the width of the cube: ";
    cin >> width >> endl;
    cout << "Enter the height of the cube: ";
    cout << "Your volume is: " << volume;
    cout << "Press any key to exit :)";
    cin.get();

    return 0;

我是C ++的新手，在我的基础计算机编程课程中，我们不得不做一些可以计算体积的事情，有人可以帮助我解决此错误吗?

I am new to C++ and in my basic computer programming class we had to make something that can calculate volume, can someone please help me in fixing this error?

推荐答案

std :: endl 用于输出流，而不用于输入流.我认为这对初学者是否有意义，因为您可以将换行符(并且大多数情况下必须从用户那里获取输入)放入输入流，但是 std :: endl根本不适用于 std :: cin .

std::endl is used for output stream not for input stream. I'd argue with that if it makes sense to a beginner, because you can put newline (and most of the time have to if you want to grab input from the user) into the input stream, but std::endl simply doesn't work with std::cin.

此外，我认为您并不需要这样做，因为当您按"Enter"键确认输入的换行符时，也将其打印到输出流中.

Besides I believe you don't really need to do it, because when you press "Enter" key to confirm your input newline character is also being printed to output stream.
