c++ string trim函數實現

#include <string>#include <algorithm>#include <functional>using namespace std;inline string&  LeftTrim(string   &str){    string::iterator   iter=find_if(str.begin(),str.end(),not1(ptr_fun<int>(::isspace)));    str.erase(str.begin(),iter);    return  str;}inline  string&  RightTrim(string   &ss) {         string::reverse_iterator  rev_iter=find_if(str.rbegin(),str.rend(),not1(ptr_fun<int>(::isspace)));    str.erase(rev_iter.base(),str.end());    return   str;}inline  string&   Trim(string   &st){     return LeftTrim(RigtTrim(st));}
