C++實現字符串分割(split)

// 字符串分割 
const std::vector<std::string> SplitString(const std::string& strSrc, const std::string& pattern)
{
	std::string str = strSrc;
	std::string::size_type pos;
	std::vector<std::string> vecStr;
	str += pattern;			//擴展字符串以方便操作
	std::size_t iSize = str.size();
	for (size_t i = 0; i < iSize; i++)
	{
		pos = str.find(pattern, i);
		if (pos < iSize)
		{
			string strSub = str.substr(i, pos - i);
			vecStr.emplace_back(strSub);
			i = pos + pattern.size() - 1;
		}
	}
	return vecStr;
}
