c语言的一些常见的算法以及思考和改进的文章,写的很不错,花费了很大的精力从网络了搜罗的,希望大家喜欢.

电脑出题人来做C语言模拟[原创] 
程序运行效果：计算机随即产生一个四位数，然后让人来猜，并且每次提示猜对的位数，直到用户猜对为止。如某次运行结果如下，计算机随即产生5130，我猜的过程如下：

Guess what number I have thought of:4567

I am sorry.You are wrong.Only 0 digits are right.Try another one.1234

I am sorry.You are wrong.Only 1 digits are right.Try another one.1235

I am sorry.You are wrong.Only 1 digits are right.Try another one.1432

I am sorry.You are wrong.Only 1 digits are right.Try another one.1345

I am sorry.You are wrong.Only 0 digits are right.Try another one.1234

I am sorry.You are wrong.Only 1 digits are right.Try another one.2431

I am sorry.You are wrong.Only 1 digits are right.Try another one.2234

I am sorry.You are wrong.Only 1 digits are right.Try another one.3234

I am sorry.You are wrong.Only 1 digits are right.Try another one.4231

I am sorry.You are wrong.Only 1 digits are right.Try another one.5231

I am sorry.You are wrong.Only 2 digits are right.Try another one.5131

I am sorry.You are wrong.Only 3 digits are right.Try another one.5132

I am sorry.You are wrong.Only 3 digits are right.Try another one.5133

I am sorry.You are wrong.Only 3 digits are right.Try another one.5134

I am sorry.You are wrong.Only 3 digits are right.Try another one.5135

I am sorry.You are wrong.Only 3 digits are right.Try another one.5136

I am sorry.You are wrong.Only 3 digits are right.Try another one.5137

I am sorry.You are wrong.Only 3 digits are right.Try another one.5138

I am sorry.You are wrong.Only 3 digits are right.Try another one.5139

I am sorry.You are wrong.Only 3 digits are right.Try another one.5130

Great!You are right.The number I have thought of is:5130

好了，代码是这样的：
