在C ++中，我认为你可以做“字符串时间2” = stringstring？ [英] In C++, I thought you could do "string times 2" = stringstring?

问题描述

我想弄清楚如何打印字符串几次。我收到错误。我只是试了一下：

I'm trying to figure out how to print a string several times. I'm getting errors. I just tried the line:

cout<<"This is a string.  "*2;

我希望输出：这是一个字符串，这是一个字符串，但我didn不知道。这行有什么问题吗？如果没有，这里是整个程序：

I expected the output: "This is a string. This is a string.", but I didn't get that. Is there anything wrong with this line? If not, here's the entire program:

#include <iostream>
using namespace std;


int main()
{
  cout<<"This is a string.  "*2;

  cin.get();
  return 0;
}

我的编译器不打开，因为我在做病毒扫描，所以我可以不给出错误消息。但是鉴于这个网站的代码相对简单，我希望有人知道我是否通过简单的查找做错了。

My compiler isn't open because I am doing virus scans, so I can't give the error message. But given the relative simplicity of this code for this website, I'm hoping someone will know if I am doing anything wrong by simply looking.

感谢您的反馈。

推荐答案

理想情况下，您可以使用循环 / strong>。检查 / while / do-while 方法。

Well, ideally, you would use a loop to do that in C++. Check for/while/do-while methods.

#include <iostream>
#include <string>

using namespace std;

int main()
{
    int count;
    for (count = 0; count < 5; count++) 
    { 
        //repeating this 5 times
        cout << "This is a string.  ";           
    }

    return 0;
}

输出：

This is a string.  This is a string.  This is a string.  This is a string.  This is a string.
