Hello World C

Program 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.

  1. How to write C program

  2. How to compile C program

  3. 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.

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.
