C + + String class takes the left and right substrings of a string (with a specific substring as a dividing line)

Example3.cpp: Defines the entry point of the console application. The left and right substrings of the string include "StdAfx.h" #include <string> #include <iostream>using namespace Std;int Main, with a specific word as the boundary. (void) {string Str,str1,str2;int index;str= "CJC is a good boy";cout<< "the original string is \" "<<str<<" \ "." <<endl;index=str.find ("good"); Str2=str.substr (index), Str1=str.assign (Str.c_str (), index);cout<< "the Left string is \ "" <<str1<< "\". " <<endl;cout<< "the right string is \" "<<str2<<" \ "." <<endl;system ("pause"); return 0;}
