请问一下这个程序还有哪错了，真的看不出来了

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[]) 
{
    char cName[5][10]={"zhangsan","lisi","wangwu","zhaoliu","qianqi"};
    int a,b,temp,pos;
    float fScore[5]={55.0,79.0,88.0,98.0,66.0,};
    
    printf("排序前:\n");
    for(a=0;a<5;a++)
    {
        printf("%s   %.2f\n",cName[a],fScore[a]);
    }
    
    printf("\n\n");
    printf("排序后:\n");
    
    for(a=0;a<4;a++)
    {
        temp=fScore[a];
        pos=a;
        for(b=a+1;b<5;b++)
        {
            if(fScore[b]>temp)
            {
                temp=fScore[b];
                pos=b;
            }
        }     
        
        fScore[pos]=fScore[a];
        fScore[a]=temp;
    }
    for(a=0;a<5;a++)
    {
        printf("%s  %.2f\n",cName[a],fScore[a]);
    }
    return 0;
}

你只交换了成绩，没有交换名字
