IDE是VS2013.

#include<iostream>#include <vector>#include<string>using namespace std;vector<string> split(const string& src, string separate_character){vector<string> strs;int separate_characterLen = separate_character.size();//分割字符串的长度,这样就可以支持如“,,”多字符串的分隔符int lastPosition = 0, index = -1;while (-1 != (index = src.find(separate_character, lastPosition))){strs.push_back(src.substr(lastPosition, index - lastPosition));lastPosition = index + separate_characterLen;}string lastString = src.substr(lastPosition);//截取最后一个分隔符后的内容if (!lastString.empty())strs.push_back(lastString);//如果最后一个分隔符后还有内容就入队return strs;}int _tmain(int argc, _TCHAR* argv[]){string s = "12.45.78";string del =".";vector<string> strs = split(s,del);for (int i = 0; i < strs.size(); i++){cout << strs[i]<<' ';}cout << endl;system("pause");return 0;}

运行结果：
