用C語言編寫：十進制轉換爲二進制

在visual C++ 6.0中，用C語言編寫，十進制轉換爲二進制的程序

操作方法

（01）打開visual C++ 6.0-文件-新建-文件-C++ Source File

（02）定義數組和變量：#include <stdio.h>#include <stdlib.h>void main(){int i, j, n, m;                              /*定義變量i,j,n,m*/int a[16] ={0};                              /*定義數組a,元素初始值爲0*/system("cls");                              /*清屏*/

（03）輸入十進制數：printf("請輸入一個十進制數(0~32767):n");scanf("%d", &n);                         /*輸入n的值*/

（04）計算二進制數：for (m = 0; m < 15; m++)                     /*for循環從0到14，最高爲符號位，本題始終爲0*/{i = n % 2;                               /*取2的餘數*/j = n / 2;                               /*取被2整除的結果*/n = j;                                   /*將得到的商賦給變量n*/a[m] = i;                                /*將餘數存入數組a中*/}

（05）輸出二進制數：for (m = 15; m >= 0; m--){printf("%d", a[m]);                      /*for循環，將數組中的16個元素從後往前輸出*/if (m % 4 == 0)printf(" ");                         /*每輸出4個元素，輸出一個空格*/}printf("n");

（06）完整的源代碼：#include <stdio.h>#include <stdlib.h>void main(){int i, j, n, m;                              /*定義變量i,j,n,m*/int a[16] ={0};                              /*定義數組a,元素初始值爲0*/system("cls");                              /*清屏*//*輸出雙引號內普通字符*/printf("請輸入一個十進制數(0~32767):n");scanf("%d", &n);                         /*輸入n的值*/for (m = 0; m < 15; m++)                     /*for循環從0到14，最高爲符號位，本題始終爲0*/{i = n % 2;                               /*取2的餘數*/j = n / 2;                               /*取被2整除的結果*/n = j;                                   /*將得到的商賦給變量n*/a[m] = i;                                /*將餘數存入數組a中*/}for (m = 15; m >= 0; m--){printf("%d", a[m]);                      /*for循環，將數組中的16個元素從後往前輸出*/if (m % 4 == 0)printf(" ");                         /*每輸出4個元素，輸出一個空格*/}printf("n");}
