c语言小程序,求高人指点
口袋中有red,yellow,blue,white,black 五种颜色的球若干个,每次从口袋中先后取出3个球,问得到3种不同颜色的球的可能取法,输出每种排列的情况。自己写的程序如下,可是总有error运行不了,求高人指点。
#include <stdio.h>
int main ()
{
enum Color {red,yellow,blue,white,black};
enum Color i,j,k,pri;
int n,loop;
n=0;
for(i=red;i<=black;i++)
for(j=red;j<=black;j++)
if(i!=j)
{
for(k=red;k<=black;k++)
if((k!=i)&&(k!=j))
{
n=n+1;
printf("%-4d",n);
for(loop=1;loop<=3;loop++)
{
switch(loop)
{
case 1:pri=i;break;
case 2:pri=j;break;
case 3:pri=k;break;
default:break;
}
switch (pri)
{case red :printf("%-10s","red");break;
case yellow: printf("%-10s","yellow");break;
case blue :printf("%-10s","blue");break;
case white:printf("%-10s","white");break;
case black:printf("%-10s","black");break;
default:break;
}
}
printf("\n");
}
}
printf("\ntotal :%5d\n",n);
return 0;
}
