Problem E: 調用函數，整數逆序輸出

#include<stdio.h>
int reverse(int number)//定義函數 
{
    int i,result=0;//result用於儲存結果 
    while(number!=0)
    {
        result=result*10;
        i=number%10;
        number=number/10;
        result=result+i;
    }
    return result;
}

int main(void)//主函數 
{
    int n;
    while(scanf("%d",&n)!=EOF)
    {
        printf("%d",reverse(n));
        printf("\n");
    }
    printf("\n");
    return 0;
}
