第十八章 6string型字符串的替换 简单

#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;

	
	return 0;
