输出一个整数的每一位

#include<stdio.h>#include<stdlib.h>int main(){     int num = 0;     int i = 0;     int a[32] = {0};     int count = 0;     printf("请输入一个整数:");     scanf("%d",&num);     while(num)        //计算位数     {         a[i] = num % 2;         num = num/2;         count++;     }     printf("二进制序列为：");     for(i = 0;i < count;i++)     {         printf("%d",a[i]);     }     system("pause");       return 0;}
