How to run C, C++ program in Linux, Ubuntu. This question is asked by a reader on my Facebook page. He started using Ubuntu and written C program but he didn’t know how to compile and run this program.
In this post, I’ll show how to create, compile and run C, C++ Pprogram in Linux, Ubuntu.
How to Run C, C++ Program in Linux, Ubuntu
1. To run a C program in Linux we first need to install Build essential package. Build essential package install development libraries require for compilation.
In Ubuntu, we install packages through the apt-get package manager. If you are not familiar with apt-get then read my previous tutorial on a apt-get package manager.

vi firstprogram.c |
|

#include <stdio.h> void main() { printf("My first Program"); } |
In vi editor, we use wq command for save and exit. Type wq once your program is completed.
|

:wq |
3. Now compile this program.

cc firstprogram.c |
5. Once it compiles successfully, then you can execute this program using a.out .
|
1 |
./a.out |
How to Run C++ program in Linux
