【C++】C++ 输入10个国家名称，用指针数组实现排序。_c++国名排序

#include <iostream>
#include <string>
using namespace std;
int str_cmp(string str1, string str2)
{
	int len1 = str1.length();
	int len2 = str2.length();
	for (int i = 0; i < len1 && i < len2; i++) if (str1[i] != str2[i]) return str1[i] - str2[i];
	return len1 - len2;
}
int main()
{
	int len = 0, i, j;
	string str[100], temp;
	cout << "输入国家名(以'#'结束):";
	while (true)
	{
		cin >> temp;
		if ('#' == temp[0]) break;
		str[len++] = temp;
	}
	for (i = len - 1; i; i--)
		for (j = 0; j < i; j++)
			if (str_cmp(str[j], str[j + 1]) > 0)
			{
				temp = str[j];
				str[j] = str[j + 1];
				str[j + 1] = temp;
			}
	cout << "排序后输出:" << endl;
	for (i = 0; i < len; i++)
		cout << str[i] << ' '; cout << endl;
	return 0;
}
