Today I write two simple cpp program,one is the console application ,and the second is the windows program.

here I just want to talk about the IO Redirection.As we know that the standard IO Library provide us the input and out. 

 

   sometimes such as we write the windows program ,most often we use MessageBox function to show some debug imformation. But this is not convenient. Infact Most operating systems give us a way of redirecting the input and output streams when we run a program. not just the console program ,also the windows can also redirect the io stream. below is my excution command line.

C++是一种高级的、静态ally typed、多重编程语言，它源自于Bjarne Stroustrup开发的一个“抽象机器”概念。它是通用的、具有面向对象能力的、支持运行时反射的、可移植的、跨平台的、兼容性强的、类C的语言。可以说，C++带给我们的很多便利，例如易用性，灵活性和效率等。同时，也存在着一些不足之处，比如复杂性和性能等。因此，作为一个程序员，应当善加利用，充分发挥其优势。本文将以详细地叙述C++编程语言的历史，并通过具体的代码实例、解释及分析，帮助读者深入理解这个最强大的编程语言。
