程序猿都非常懒,你懂的! 今天为大家分享的是Integer这个包装类.在现实开发中,我们往往须要操作Integer,或者各种进制的转换等等.我今天就为大家具体解说一下Integer的使用吧.看代码: package com.herman.test; public class IntegerTest { public static void main(String[] args) { System.out.println("Integer中的常量**************************
#include <stdio.h> #define N 8 //这里你要求是8位 int main(int argc, const char * argv[]) { int binary[8];//用于存放最后取得的补码 int a=0;//要处理的数值 int a1=0;//保存a的值 int m=0;//用于存放临时的数值 printf("请输入要转换成二进制补码的数的值:\n"); scanf("%d",&a); a1=a; if (a=
Every non-negative integer N has a binary representation. For example, 5 can be represented as "101" in binary, 11 as "1011" in binary, and so on. Note that except for N = 0, there are no leading zeroes in any binary representation.
