C Language Learning (1)-Environment configuration

Written in front of the words, the article is to see a set of teacher Yang's video, some of the notes made, while reading and writing, and then thank Mr. Yang.

1. The pitfalls to avoid before learning C

Myth One: C + + is an upgraded version of C; C # is an upgraded version of C + +

Myth Two: C + + is Visual C + +

Myth Three: MFC is a must-learn "advanced technology"

2. Notes on development tools

2.1 Editor (Complier): compilation is the translation process from source code to object code (machine language) that can be executed directly by the computer. The compiler for C language is: Gcc,msc++complier

Extensions: The execution of C # code is compiled two times, first compiled into intermediate language (IL) through the C # compiler, and the second compilation occurs when the EXE file generated by C # code is executed, and the instant compiler (JIT) is called to generate machine language that the machine recognizes.

2.2 Integrated development tools (IDE): The IDE generally has the following features: keyword highlighting, code automatic display, code formatting

3.GCC compilation of the first C program

Introduction to 3.1GCC

Use of 3.2GCC

First step: Download the gcc file. Put the downloaded GCC file into a directory that does not exist in the Chinese and Spaces folder.

Write the following code, named T1.c, to save the ABC folder under the E disk.

#include <stdio.h>int  main () {    printf (" hello ");     return 0 ;}

Note: Code save format to ANSI, otherwise Chinese will appear garbled.

Step Two: open cmd, enter the t1.c folder, run the compilation process, execute exe

4.EditPlus Build GCC development environment

Found every time you compile a file, you have to write a lot of duplicate code, the following describes a editplus to build a GCC build environment

Download EditPlus, and install, open. Then do the following:

Tool---"Configuring User Information---" Tool Group 1---Add tool---"Application

Such as:

4.1 Creating "GCC compilation"

Menu text: The name of the operation, its own definition

Command: Represents the program to be executed, writes the full path of the Gcc.exe

Parameter: The argument that the executing program is passing to Gcc.exe: $ (FileName)-O $ (filenamenoext). exe

Initial directory: Select "file directory", equivalent to CMD in the CD to. C folder

Action: Select "Capture Output"

Save: Select "Current file, all open files"

The interface is as follows:

Here's how to set the shortcut keys:

Tool---Shortcut---type---tool---user tool 1---New shortcut key---assignment

4.2 Creating "gcc run"

4.3 running c programs with EditPlus

1. Write the t1.c code in EditPlus, then click GCC Compile in the tool, run with GCC, and then see the results at the bottom

C language can not only write the console program, but also to make a variety of UI interface, the following c a GUI

5. Writing the first GTK program

Introduction of 5.1GTK:

Configuration of 5.2GTK:

Download the GTK and save it to the appropriate folder and configure the environment variables.

5.3GTK for use in EditPlus:

Create GTK Compilation

Configuration of the parameters:

The F in If:\gtk\include is for GTK in the F-disk;

$ (FileName)-w-o $ (filenamenoext). exe-IF: \gtk\include-IF: \gtk\include\gtk-3.0-IF: \gtk\include\cairo-IF: \GTK\INCLUDE\GDK-IF: \gtk\include\glib-2.0-IF: \gtk\lib\glib-2.0\include-IF: \gtk\include\pango-1.0-IF: \gtk\include\atk-1.0-IF: \gtk\include\gdk-pixbuf-2.0-lf:\gtk\lib-lgtk-win32-3.0-lgobject-2.0-lglib-2.0-lgdk-win32-3.0-lgdk_pixbuf-2.0-lcairo–mwindows

Enter the following code in EditPlus:

#include <stdio.h>#include<gtk/gtk.h>//Introducing GTK FilesintMainintargcChar*argv[]) {    //initializing the GTK environment without writing an errorGtk_init (null,null); //creates a new top-level window that returns the window pointergtkwidget*window=gtk_window_new (Gtk_window_toplevel); //set the form titleGtk_window_set_title (window,"Hello"); //The program exits after the setting window is closed, otherwise it cannot be seen, but the process is still there; GCC cannot be compiled at this timeG_signal_connect (window,"Destroy", gtk_main_quit,null);//    //Display windowgtk_widget_show (window); //start the message loop, no program will flash back, gtk_main generally do not write codeGtk_main (); return 0;}

After running

The first day to write here, later think of what, and then slowly modify. It's really hard to find out what you know and write it down.
