C++常用字符串分割方法
#include<string>#include<vector>#include<iostream>using namespace std;void Tokenize(const string& str, vector<string>& tokens, const string& delimiters){ // Skip delimiters at beginning. string::size_type lastPos = str.find_first_not_of(delimiters, 0); // Find first "non-delimiter". string::size_type pos = str.find_first_of(delimiters, lastPos); while (string::npos != pos || string::npos != lastPos) { // Found a token, add it to the vector. tokens.push_back(str.substr(lastPos, pos - lastPos)); // Skip delimiters. Note the "not_of" lastPos = str.find_first_not_of(delimiters, pos); // Find next "non-delimiter" pos = str.find_first_of(delimiters, lastPos); }}int main(int argc, char *argv[]){ string str("====aaa==bbb=ccc=ddd===="); vector<string>tokens; Tokenize(str, tokens, "="); for( int i = 0; i < tokens.size() ; i++ ) { cout << tokens[i] << endl; } return 0;}
