Contain all kinds of prejudice and arbitrariness, please read carefully. Why do you study in the school C, get the enterprise production does not work?And why do enterprise-class programmers still have no control over C + +? In all aspects of

Why use the word "real"? Because we start with the C language, we will first understand that the C language has and only one main function, the main function is the C language entry point and exit Point! (can refer to >) not only C language, C + +,
