C语言是一种结构化程序设计语言，它是面向过程的，在处理较小规模的程序时一般比较容易实现，而当程序规模较大时，C语言就显示出了它的不足。在这种情况下C++应运而生，C++语言是从C语言演变而来的，它保留了C语言的所有优点，同时也增加了面向对象的功能。现在C++已成为程序设计中应用最广泛的一种语言。

-C language is a structured programming language, it is a process oriented, in dealing with a smaller scale of the program is generally easier to achieve, and when the program is relatively large, C language has shown its shortcomings. In this case, C++ came into being, C++ language evolved　the C language, it retains all the advantages of C language, but also increased the object-oriented features. Now C++ has become one of the most widely used language in programming.
