How do you append an int to a string in C++?(如何在 C++ 中将 int 附加到字符串?)
问题描述
int i = 4;
string text = "Player ";
cout << (text + i);
我想打印 Player 4
.
以上显然是错误的,但它显示了我在这里尝试做的事情.有没有一种简单的方法可以做到这一点,还是我必须开始添加新的包含?
The above is obviously wrong but it shows what I'm trying to do here. Is there an easy way to do this or do I have to start adding new includes?
推荐答案
使用C++11,你可以这样写:
With C++11, you can write:
#include <string> // to use std::string, std::to_string() and "+" operator acting on strings
int i = 4;
std::string text = "Player ";
text += std::to_string(i);
