<>输入n个字符串，将他们按字母由从小到大的顺序排列并输出
方法一：冒泡排序
#include<iostream> #include<string> using namespace std; int main() { const int
n= 4; string str[n],t; int i,j; for (i = 0; i < n; i++) cin >> str[i];
//从键盘输入n个字符串 for(i=0;i<n-1;i++)//比较的趟数 for(j=0;j<n-1-i;j++)//每趟比较的次数 if (str[j]
> str[j + 1]) { t = str[j]; str[j] = str[j + 1]; str[j + 1] = t; } for (i = 0; i
< n; i++) cout << str[i] << " "; return 0; }
方法二：选择排序
#include<iostream> #include<string> using namespace std; int main() { const int
n= 4; string str[n],t; int i,j; for (i = 0; i < n; i++) cin >> str[i];
//从键盘输入n个字符串 for(i=0;i<n-1;i++)//比较的趟数 for(j=i+1;j<n;j++)//每趟比较的次数 if (str[i] >
str[j]) { t = str[j]; str[j] = str[i]; str[i] = t; } for (i = 0; i < n; i++)
cout<< str[i] << " "; return 0; }
