本文展示了一个使用C++实现的排序算法示例，其中包括对学生姓名和成绩进行排序的过程。通过对数组进行遍历和比较，实现了成绩从高到低及姓名从A到Z的排序。

#include<iostream>  
#include<string>  
using namespace std;  
const int num=20; 
int main()  
{  
    int i,j,t;  
    string temp;  
    string name[num]={"zhao","qian","sun","li","zhou","wu","zheng","wang","feng","chen","chu","wei","jiang","shen","han","yang","zhu","qin","yun","xu"};  
    double score[num]={79,84,65,89,60,92,78,56,62,55,54,16,48,99,82,100,35,85,75,20};   
    for(j=0;j<num-1;j++)  
        for(i=0;i<num-j-1;i++)  
        {  
            if(score[i]<score[i+1])  
            {  
                t=score[i];  
                score[i]=score[i+1];  
                score[i+1]=t;  
                temp=name[i];  
                name[i]=name[i+1];  
                name[i+1]=temp;  
            }  
        }  
        cout<<"按成绩排序后的结果是:"<<endl;  
        for(i=0;i<num;i++)  
            cout<<name[i]<<"\t"<<score[i]<<endl;
        cout<<endl;
        for(j=0;j<num-1;j++)  
            for(i=0;i<num-j-1;i++)  
            {  
                if(name[i]<name[i+1])  
                {  
                    temp=name[i];  
                    name[i]=name[i+1];  
                    name[i+1]=temp;  
                    t=score[i];  
                    score[i]=score[i+1];  
                    score[i+1]=t;  
                }  
            }  
            cout<<"按同学姓名排序后有结果是:"<<endl;          
            for(i=0;i<num;i++)  
                cout<<name[i]<<"\t"<<score[i]<<endl;  
			return 0;
}

运行结果：
