程序代码：

#include<stdio.h>

int right(unsigned value,int n){
    unsigned z;
    z=(value>>n)|(value<<(16-n));
    return z;
}
int left(unsigned value,int n){
    unsigned z;
    z=(value>>(16-n))|(value<<n);
    return z;    
}
int main(){
    unsigned a;
    int n;
    printf("input:\n");
    scanf("%o",&a);
    printf("input:\n");
    scanf("%d",&n);
    if(n>0){
        right(a,n);
        printf("the result is:%o\n",right(a,n));
    }
    else{
        n=-n;
        left(a,n);
        printf("the result is :%o\n",left(a,n));
    }
    return 0;
}

z=(value>>n)|(value<<(16-n));
