Code blocks is an open-source & powerful C/C++ compiler that has the support of many GNU tools such as GDB. GDB is a GNU debugger that is used to debug C/C++ programs.

In this article, we will see how to download and install code blocks IDE on our computers.

Download & Install code blocks :

Click on this link to download code blocks.

After downloading the .exe file, Right-click on the executable, select Run as administrator and follow onscreen instructions to install code blocks in your computer.

Creating a new project:

After installation, open Code Blocks IDE and click on File > New > Project.

  • Select the application type as a console application and click on Go.
  • In the next window, select C as your language and click on next.
  • Give a meaningful project name in the next window and click on next. Finally, we have created a C project in Code Blocks.

Code, compile & build:

In the left side panel, click on the project name to expand the project tree and click on “Sources > main.c“. Copy and paste the below source code in the editor and click on “build & run” in the top menu bar.

#include <stdio.h>
int main()
    printf("Hello, world!");
    return 0;

We have successfully created, compiled, and executed the C program in CodeBlocks IDE.

Configuring the GNU Debugger:

Now click on “Settings” in the top menu bar and select Debugger. In the left side menu-> select “Default” under “GDB/CDB Debugger”. In the right-side panel, click on […] and select the executable path of “gdb.exe”  and click on OK.

gdb.exe Executable path : C:\TDM-GCC-64\gdb64\bin\gdb.exe

Debugging the program:

Now if you see, there will be line numbers visible at the left side of the program. Just click right beside the line number you will see a red dot appeared at that point. That is known as the Breakpoint. Now the execution of the program will stop at this point if you compile and run it.
