混沌演示——数据加密的动态过程以及结果展示(Chaos demo- data encryption as well as the results demonstrate the dynamic process)

this is a fairly simple code that determines whether the integer you will enter is odd or even. Based on your choices by the questions asked by the program, the ouput background and foreground will change. and one thing: please don t enter such numbers as 0987 or .983 as they are not integers!
