#include<stdio.h>
3include<string>
void  main() {
         int  i;
         char*  a[5]={"student","worker","cader","soldier","peasant"};
         char  *p1,  *p2;
         p1=p2=a[0];
        for(i=0;i<5;i++) {
                  if(strcmp(a[i], p1)>0)  p1=a[i];
                  if(strcmp(a[i], p2)<0)  p2=a[i];
        }
        printf("5s  %s\n",p1,p2);
}

我知道答案是Worker    cader
我就想知道它的详细的解题步骤和思路
