C程序练习-无重复的三个数(2)

    上次那个用C语言写的是一个连续的四个数，因此，写完后，我在想，如果这四个数不是连续的四个数，我们该如何去做呢？我第一个想到的是，把这四个数存在数组中，如果循环读取这个数组。因此代码和上次写的很类似。代码如下：

#include <stdio.h>

int main(int arc,char *argv[])
{
    int num[4]={1,3,6,8};
    int i,j,k;
    int count=0;
    for(i=0;i<4;i++)
    {
                    for(j=0;j<4;j++)
                    {
                                    for (k=0;k<4;k++)
                                    {
                                        if (num[i] != num[j] && num[i] != num[k] && num[j] != num[k] )
                                        {
                                           if (count++ % 5 == 0)
                                           {
                                              printf("\n");
                                           }
                                           printf("%d%d%d ",num[i],num[j],num[k]);
                                         }
                                    }
                    }
    }
    printf("\n count=%d",count);
    system("pause");
}
