Hello World CProgram With Code Blocks
Here, we will learn that how to write c program in Code Blocks and how to use Code Blocks to write hello world C program and for C programming.
But before starting programming with C language, we need to know these three things.
How to write C program
How to compile C program
How to run C program
Three steps to create any C program :
We will have to follow at least three steps to create any C program. All the three steps are given below.
1 Writing C Program : We can use any text editor for writing C program like Windows's Notepad editor, Linux's Vim editor etc.
2 Compiling C Program : For compiling C program, we need a compiler software. A compiler is a special computer program that transforms source code written in a programming language into binary or machine language. As you remember that we have already discussed What is a compiler? in previous section.
3 Running C Program : To run C program, we need a platform like Windows/Ubuntu/Linux.
Integrated Development Environment (IDE) : With IDE, we can get all these steps at one place and IDE makes development easy.
C Hello World
Now, we will see that how to write C hello world program with Code blocks IDE.
Following steps, We need to follow for creating hello world C program with Code Blocks :
1 Open Code Blocks : Go to Desktop and double clicks on Code Blocks icon or click on Windows's start menu and then click on All Programs and find Code Blocks from list and click on it.
2 After Opening : Click on File Menu and then click on New option and then click on Empty File or press Ctrl+N.
3 Type or Enter Code : Type or enter code like this.
4 Save Source File : Click on File Menu and select Save File option or press Ctrl+S. After that a window will open and on this window type File name with c or cpp extension like hello.c / hello.cpp after that click on Save button.
5 Run Program : Click on Build Menu and select Build and run option or press F9. After that a window will open.
Once you have done with build and run the program. now go to that directory or folder where you saved your C source file. inside this folder, you will get an executable file like hello.exe. You can run this executable file directly clicking double.
6 congratulations !!, You have been successfully run your first C program with Code Blocks IDE.
Info : We will understand this program in coming sections, that why we wrote
main, int , getch, printf etc in this program.
