C++分割字串

#include <iostream>#include <string>#include <vector>using namespace std;/*功能：字串分割傳回值: 分割後的字串數組參數：str：原字串pattern：分隔字元*/vector<string> split(const string &str, const string &pattern){int current, pos, patlen;vector<string> result;patlen = pattern.length();current = pos = 0;while( current < str.length() ){pos = str.find(pattern, pos);if( string::npos == pos ){result.push_back( str.substr(current) );break;}if( current != pos )result.push_back( str.substr(current, pos-current) );pos += patlen;current = pos;}return result;}//測試程式int main(){string str = "AAsldfAAjsljAAsfjoeAAeorAsdofAA";vector<string> vec = split(str, "AA");for(int i=0; i<vec.size(); i++)cout << vec[i] << endl;return 0;}
