Introduction to recursive functions 1. A function is a self-called function. It calls itself directly or indirectly within the function body, that is, the function itself is nested.For example, the function fact (int n) in the following program is to evaluate n!# Include "stdio. H"# Include "conio. H"Long fact (int n){If (n = 1)Return 1;Return (fact (n-1) * N;}Main (){Int n = 0;Long factofn = 0;Printf ("enter a positive integer/N ");Scanf ("%

input/output of the port in VC ++ can be achieved through the port I/O function in p and ou tp.

callback.In windows, WndProc is a typical form of callback.In a general program, callback functions are not very effective. You can skip this form.The main purpose is to call a function when it is not in the same file, such as a dynamic library.Functions in other programs only adopt callback.# Include "stdio. h"# Include "conio. h"Int add (int a, int B );Int libfun (int (* pDis) (int a, int B ));Int main (void){Int (* pfun) (int a, int B );Pfun = add

In linux, if the input value of getch () is not displayed, linuxgetch In linux, C programs are developed, but the system does not support the conio. h header file. getch () cannot be used to not echo the function. The following example shows how to build a function to achieve non-echo of numeric input. 1 # include Running result: Note: in Linux, when C Programming encounters the problem of entering a password, the password cannot be seen at the time

Virtual functions are an important concept in Object-Oriented C ++. Because it fully embodies the inheritance and polymorphism features in object-oriented thinking, it is widely used in C ++. For example, in Microsoft's MFC class library, you will find that many functions have virtual keywords, that is, they are all virtual functions. It is no wonder that virtual functions are the essence of the C ++ language. So what is a virtual function? Let's take a look at Microsoft's explanation: A vir

This example shows how to use the STL queue container. To add data to the queue, you only need to use Q. push (item), but Q is not used to retrieve data. pop (), but Q. front () retrieves the first data, Q. pop () is to extract the first data queue, and its return value is void. 1 /**/ /* 2 (C) oomusou 2006 Http://oomusou.cnblogs.com 3 4 Filename: queue. cpp 5 Compiler: Visual C + + 8.0 6 Description: Demo How to Use Queue 7 Release: 11/25/2006 8 */ 9 # Include

Alloc. h indicates memory management functions (such as allocation and release ). Assert. h defines assert debugging macros. BiOS. h describes the various functions that call the IBM-PC rom bios subroutine.
