将十六进制显示为点分十进制

#include <stdio.h>
int main()
{
    int src=0xffffffff;
    printf("请输入十六进制地址：");
    while(scanf("%x",&src)!=EOF)
    {
        int res[4];
        int times=4;
        while(times>0)
        {
            int temp=0x000000ff;
            temp=temp&src;            
            res[times-1]=temp;
            src=src>>8;
            times--;
        }
        for(times=0;times<4;times++)
        {
            printf("%d",res[times]);
            if(times<3) {putchar(‘.‘);}
            else {putchar(‘\n‘);}
        }
        printf("请输入十六进制地址：");
    }
    return 0;
