使用函数输出一个整数的逆序数：输入一个整数，将它逆序输出。要

#include<stdio.h>
int reverse(int number){
    int sum=0,s;
    if(number == 0){
        return 0;
    }else if(number >= 0){
        while(number != 0){
            sum = sum*10;
            s = number%10;
            number /= 10;
            sum = sum+s;
        }
        return sum;
    }else{
        number = -number;
        while(number != 0){
            sum = sum*10;
            s = number%10;
            number /= 10;
            sum = sum+s;
        }
        return -sum;
    }
}
int main(){
    int number;
    printf("请输入任意一个整数：");
    scanf("%d",&number);
    printf("%d的逆序输出为：%d\n",number,reverse(number));
    return 0;
}
