十二硬币的C语言判别

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)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 void main()int i;float a12;for(i=0;ia11) printf(There is a special coin:%f(12) and its lighter than others.n,a11); else printf(There is a special coin:%f(12) and its heavier than others.n,a11); else if(a0+a1+a2a8+a9+a10) if(a8=a9) printf(There is a special coin:%f(11) and its lighter than others.n,a10); else if(a8a9) printf(There is a special coin:%f(10) and its lighter than others.n,a9); else printf(There is a special coin:%f(9) and its lighter than others.n,a8); else if(a8=a9) printf(There is a special coin:%f(11) and its heavier than others.n,a10); else if(a8a9) printf(There is a special coin:%f(9) and its heavier than others.n,a8); else printf(There is a special coin:%f(10) and its heavier than others.n,a9); else if(a0+a1+a2+a3a4+a5+a6+a7) if(a0+a2+a5=a1+a4+a8) if(a6=a7) printf(There is a special coin:%f(4) and its heavier than others.n,a3); else if(a6a7) printf(There is a special coin:%f(8) and its lighter than others.n,a7); else printf(There is a special coin:%f(7) and its lighter than others.n,a6); else if(a0+a2+a5a1+a4+a8) if(a0=a2) printf(There is a special coin:%f(5) and its lighter than others.n,a4); else if(a0a2) printf(There is a special coin:%f(1) and its heavier than others.n,a0); else printf(There is a special coin:%f(3) and its heavier than others.n,a2); else if(a1a8) printf(There is a special coin:%f(2) and its heavier than others.n,a1); if(a5a7) printf(There is a special coin:%f(7) and its heavier than others.n,a6); else printf(There is a special coin:%f(8) and its heavier than others.n,a7); else if(a0+a2+a5a2) printf(There is a special coin:%f(3) and its lighter than others.n,a2); else printf(There is a special coin:%f(1) a
