Executing C Programs on a Linux Environment
Learn how to install Linux on your machine, and practice compiling and running C programs on a Linux environment.
We'll cover the following
Install Linux
You can install Linux on your local machine and, then, create and execute programs. You can download the Ubuntu Linux from here.
Step 1: Write source code
You can type the program into any suitable editor. Type the program in a text editor and save it as hello.c
. After that, you will need to compile and execute the program.
Step 2: Compile the program using the gcc compiler
Compile the program using the gcc
compiler or by running either one of the following commands:
gcc hello.c
gcc hello.c -o hello.out
By default the executable code for any program is stored in the file: a.out
. To store it in any other file use the switch, –o filename
.
Step 3: Execute the program
After the successful compilation of the program, you have to execute it. ./a.out
means execute a.out
from the current directory. Execute the program by running one of the following commands:
./a.out
./hello.out
