陈大师真强哈^

第四道做起来没那么简洁

#include <stdio.h>
main()
{
    int n,fen1,fen2,fen5,count=0;

    scanf("%d",&n);
    for(fen5=1;fen5<=20;fen5++)
     for(fen2=1;fen2<=50;fen2++)
         for(fen1=1;fen1<=100;fen1++)
             if(5*fen5+2*fen2+fen1==n)
                 count++;
             printf("count=%d\n",count);
    for(fen5=1;fen5<=20;fen5++)
     for(fen2=1;fen2<=50;fen2++)
         for(fen1=1;fen1<=100;fen1++)
             if(5*fen5+2*fen2+fen1==n)
                 printf("fen5:%d  fen2:%d  fen1:%d\n",fen5,fen2,fen1);
}
