程序代码：

#include<stdio.h>

#define M 5

void fun(int a[],int b[],int n,int m,int s);
void print(int k[]);

int main()
{
    int a[]={1,2,3,4,5,6,7,8,9,0};

    int b[M]={0};

    fun(a,b,0,0,sizeof(a)/sizeof(*a));

    return 0;
}

void fun(int a[],int b[],int n,int m,int s)
{
    int i=0;

    for (i=n;i!=s;++i)
    {
        b[m]=a[i];

        if (m<M-1)
            fun(a,b,i+1,m+1,s);
        else
            print(b);
    }
}

void print(int k[])
{
    int i=0;

    for (;i!=M;++i)
        printf("%3d",k[i]);

    printf("\n");
}
