• C++分割字符串std::string
• • 代码如下

将字符串str按照分割的字符串s，进行分割，将结果以std::vectorstd::string形式返回。
如str=“110.22,120.22,130.22,140.22”
s=","
std::vectorstd::stringret=[“110.22”,“120.22”,“130.22”,“140.22”];

#include

#include 

std::vector splitString(const std::string& str, const std::string& s)
{
	std::vector ret;
	int sLen = s.size();
	int index = 0;
	int endIndex = str.find(s, index);
	while(endIndex > 0)
	{
		if(endIndex > index)
		{
			std::string temp = str.substr(index, endIndex-index);
			ret.push_back(temp);
			index = endIndex + sLen;
		}
		endIndex = str.find(s, index);
	}
	if(index < str.size() )
	{
		std::string temp = str.substr(index, str.size() - index);
		ret.push_back(temp);
	}
	return ret;
}
