关于enum 的 代码不知道哪里出了错
#include<stdio.h>main()
{
enum fruit{apple,orange,banana,pinapple,pear};
enum fruit x,y,z,pri;
int n, loop;
n=0;
for(x=apple;x<=pear;x++)
for(y=apple;y<=pear;y++)
if(x!=y)
{
for(z=apple;z<=pear;z++)
if((z!=x)&&(z!=y))
n++;
printf("\n%-4d",n);
for(loop=1;loop<=3;loop++)
{
switch(loop)
{
case1: pri=x; break;
case2: pri=x; break;
case3: pri=z; break;
default: break;
}
switch(pri)
{
case apple: printf("%-8s","apple"); break;
case orange: printf("%-8s","orange"); break;
case banana: printf("%-8s","banana"); break;
case pinapple: printf("%-8s","pinapple"); break;
case pear: printf("%-8s","pear"); break;
default: break;
}
}
printf("\ntotal %d",n);
}
}
