C ++向量到字符串 [英] C++ vector to string
本文介绍了C ++向量到字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个向量< int>
容器有整数(例如{1,2,3,4}),我想转换为一个字符串的形式
I have a vector<int>
container that has integers (e.g. {1,2,3,4}) and I would like to convert to a string of the form
"1,2,3,4"
在C ++中最干净的方法是什么?
在Python中,这是我该怎么做:
What is the cleanest way to do that in C++? In Python this is how I would do it:
>>> array = [1,2,3,4]
>>> ",".join(map(str,array))
'1,2,3,4'
推荐答案
绝对不像Python那么优雅,但在C ++中没有什么比Python那么优雅。
Definitely not as elegant as Python, but nothing quite is as elegant as Python in C++.
使用 stringstream
...
std::stringstream ss;
for(size_t i = 0; i < v.size(); ++i)
{
if(i != 0)
ss << ",";
ss << v[i];
}
std::string s = ss.str();
您也可以使用 std :: for_each
。
