最好使用std :: string或std :: stringstream [英] Better to use std::string or std::stringstream

问题描述

我有一个"printf"样式功能:

Hi,

I have a "printf" style function:

void myclass::write (int, char *, ...)

此函数采用通常的printf样式参数.我正在执行的转换是使用简单的vsprintf.字符串转换后，需要将其存储以供以后打印(通过std :: cout接口).字符串转换后，将不再对其进行任何处理.它们只是打印出来的.

1.将字符串存储在std :: string中更好吗?
2.将字符串存储在std :: stringstream中更好吗?
3.是否有更好的存储空间?


谢谢.

This function takes the usual printf style params. The conversion I am doing is using the simple vsprintf. After the string is converted, it needs to be stored for later printing (through a std::cout interface). After the strings are converted there is no more processing done on them; they are just printed.

1. Is it better to store the strings in std::string?
2. Is it better to store the strings in std::stringstream?
3. Is there a better storage for this?


Thanks.

推荐答案

由于只需要存储一个字符串，请使用std::string.

Since you only need to store a string, use std::string.
