1. What is the idea of object-oriented program design? A: The data structure and the methods of operation of the data structure are encapsulated to form an object. 2. What is a class. A: Classify objects that have commonalities to form a set,

The maximum number of random numbers in C + + is Rand_max, defined in header file . Under Windows platform vs is 0x7fff, the Xcode of the MacBook is the maximum value for int. It seems that different platforms are different. But Windows is too damn

Excerpt from "C and pointers" Two applications of function pointers: I. callback function, the approximate template is as follows: int fun (int a,int (*com) (void const *a,void const *b)); COM here is a callback function, that is, the user needs to

#if vs. if Conditional compilation is the content of the preprocessing section in C language, which is the first part of the compiler's compilation of code. Conditional compilation contains judgment statements, such as #if, #else, #elif, and #endif

It seems that the foundation is still very important, the foundation is not solid hard to learn C language, do not say to write high quality C language code. Today, I was tortured by this problem, haha, but now finally understand the ' 0 ', "0"

Do not remember who said, can use the const when possible to use the Const. Indeed, Const makes a great contribution to increasing the robustness of the program, but the const modifier pointer is noteworthy. A pointer to a const object; If the
