#include<iostream>
using namespace std;
int main()
{
	string str = "hello";
	string s = "Hahah";
	str.insert(1, s);//在原串下标为1的字符e前插入字符串s
	cout << str << endl;

	string str1 = "hello";
	char c = 'w';
	str1.insert(4, 5, c);//在原串下标为4的字符o前插入5个字符c
	cout << str1 << endl;

	string str2 = "hello";
	string s2 = "weakhaha";
	str2.insert(0, s2, 1, 3);//将字符串s2从下标为1的e开始数3个字符，分别是eak，插入原串的下标为0的字符h前
	cout << str2 << endl;

	return 0;
