十二硬币的C语言判别(共5页)

1、精选优质文档-倾情为你奉上十二硬币判别代码 人间客制作国外流行的12个硬币问题：12硬币中可能有一个假的，而且不知道假币比真币重还是轻，给你一架天平，天平没有示数，只能判断是平衡还是不平，且只准称三次，让你判断是否有假币；如果有，找出来。解法思想如下：第一步：任选8个比较，如选： 比 一、若一样重，则假币在中，第二步： 比1.若一样重，则可能的假币为。则第三步： vs 1)若一样重，则没有假币；2)不一样重，则假币为：如果(1)>(12)，则假币轻，反之，假币重； 2.若重，则第三步： 比 1)若一样重，则假币为（较轻）2)不一样重，则假币为、中较重者3.若轻，则第三步： 比 1)若一样

2、重，则假币为（较重）2)不一样重，则假币为、中较轻者二、若重，则第二步： 比 1.若一样重，则假币在中，第三步： 比 假币为、中较轻者2.若端较重，则假币在中，第三步：比 1)若一样重，则假币为（较轻）2)不一样重，则假币为中较重者3.若端较重，则假币在中，第三步： 比 1)若一样重，则假币为（较轻）2)不一样重，则假币为、中较重者三、若轻，则与上面类似，第二步：比 1.若一样重，则假币在中，第三步： 比 假币为、中较重者2.若端较轻，则假币在中，第三步： 比 1)若一样重，则假币为（较重）2)不一样重，则假币为中较轻者3.若端较轻，则假币在中，第三步： 比 1)若一样重，则假币为（较重）2)

3、不一样重，则假币为、中较轻者在科技发达的时代，我们都不愿意去做这样繁琐的比较，而是想借助于计算机的威力，下面给大家介绍一种方法，可以在很短的时间内完成中比较。当然，这类问题转化到编程上去后，主要考查的是大家的编程思想，而不再是12硬币问题本身了，因为12个硬币的重量需要大家自己去输入，这些数据只是为了检验大家程序的正确与否。下面是该问题的代码：#include <stdio.h>void main()int i;float a12;for(i=0;i<12;i+)scanf("%f",&ai);if(a0+a1+a2+a3=a4+a5+a6+a7)
