1. getchar () is stdio. the library function in H reads a character from the stdin stream. That is to say, if stdin has data, it can be directly read without entering it. Getch () and getche () are library functions in conio. H. They are used to

Preparatory work First of all, because here is only in the C language verification algorithm, so there is no good interface to do optimization, ugly is deserved. Knowing how the game works, you can actually describe the game as four identical

After returning more than 1000 posts and judging nearly papers, I took a long breath. Recently, the serial port solution has finally been finalized, and it will soon end. Otherwise, it will take a lot of time and delay is the devil. I found a code

Console Application Development on the text interface is the easiest way to thoroughly learn C ++ and master the implementation methods of the interactive system. However, the C ++ library of Visual C ++ does not have the text (character) screen

If you do not press enter, you will receive one character input!Remember to write a log (http://blog.csdn.net/anyue417/archive/2006/08/14/1064145.aspx) a few days ago, such as the following program problems:The Code is as follows: # Include Void

A comprehensive and systematic explanation of functions. The first thing that comes to my eye is a strange method of function declaration: Main () {double sum, atof (char []); // function declaration char line [maxline]; int Getline (char line [],

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,
