每当我在C ++中输入cin的空格时，我的代码都会跳过行 [英] My code skips lines whenever I type in a space into the cin in C++

问题描述

当我键入一个单词输入或仅输入数字时，代码似乎工作正常但是只要我输入空格键它就会跳过代码中的行。这只是我们的第一个家庭作业，所以我知道它不应该是非常复杂的。它可能只是我的软件吗？有人愿意帮助我吗？

Code seems to work fine when I type in one word inputs, or only numbers but as soon as I type in a spacebar it just skips lines in the code. This is only the first homework that we have and so I know it's not supposed to be very complicated. Could it just be my software? Anyone care to help me?

// This program prompts the user a few general questions about themselves, the date, which IDE they are using, and which machine they have downloaded the IDE on to.
#include <iostream>
#include <string>
using namespace std;

int main()
{
    string userName, currentDate, softwareName, machineName;

    //Ask the user his name.
    cout << "What is your name? ";
    cin >> userName;

    //Ask the user the date.
    cout << "What is the date? ";
    cin >> currentDate;

    //Asks the user which software he downloaded.
    cout << "What is the name the IDE software you downloaded? ";
    cin >> softwareName;

    //Asks the user which machine he downloaded his IDE on.
    cout << "Which machine did you download the IDE on? (ie. home computer, laptop, etc.) ";
    cin >> machineName;

    //Prints out the users inputs going downwards.
    cout << "" <<  userName << endl;
    cout << "" <<  currentDate << endl;
    cout << "" <<  softwareName << endl;
    cout << "" <<  machineName << endl;
    return 0;
}

我的尝试：



我尝试重写代码，学会了我必须添加字符串，并且只是尝试将所有内容格式化，但似乎得到相同的输出。

What I have tried:

I've tried rewriting the code, learned I had to add string, and just tried to format everything a little neater but seem to get the same output.

推荐答案

cin 总是在分隔符上停止，包括空格。

要读取整行直到ENTER，请使用 std :: getline - cppreference.com [ ^ ]。

cin always stops on a separator, which includes space.
To read a whole line up to the ENTER, use std::getline - cppreference.com[^] instead.
