c++学习笔记——字符串插入、连续读取

题目描述：

代码实现：

#include<iostream>
#include<string>
using namespace std;
int main() {
	string s1, s2;
	while (cin >> s1 >> s2)
	{
		int index = 0;
		char c = s1[0];
		for (int i = 0; i < s1.size(); i++)
		{
			if (s1[i] < c)
			{
				c = s1[i];
				index = i;
			}
		}
		s1.insert(index + 1, s2);
		cout << s1 << endl;
	}
	return 0;
}
