#include <iostream>

#include <string>

using namespace std;



int main()

{

	//char ch1[10] = "gh";

	//char ch2[] = "abcdef";

	//strncpy(ch1,ch2,6);

	//cout<<ch1<<endl;

    

	string str1="hello word";

	//string str2="xianglingchuan";

	//支持char字符串

	//char str2[] = "xianglingchuan";

	

	//支持char型字符

	char str2='a';

	str1.replace(0,2,2,str2);

	cout<<str1<<endl;
