This is a previous time to do http://fun.coolshell.cn/in a question, very interesting, involved in fact is the basis of C, but the first time I saw this line of code really confused me:printf (&unix["\021%six\012\0"], (Unix) ["has"" Fun"0x60);At

C Language Section1. Analysis of pointersint (*p) [5] and int *p[5]The former is a pointer to an array that contains 5 elements. The latter is an array with a length of 5, and each element in the array points to an integer variable.int *f (int i,

Article 05: Understand what functions C + + silently writes and callsThe compiler defaults to declaring a default constructor, a copy constructor, a copy assignment operator, and a destructor. These functions are both public and inline. 1 class

In the C language, the representation of enumeration types, character types, and various integers is called scalar types.When you use a scalar-type value in a C expression, the compiler automatically converts those identifiers to integer saves.The

The insertion sort is a sort algorithm that does not change the original sequence (array), but instead creates a new sequence that operates on the new sequence.This is explained by the example of small to large sort.The basic idea of inserting a
