How To Compile And Run a C/C++ Code In Linux

C Programming Language is mainly developed as a system programming language to write kernels or write an operating system. C++ Programming Language is used to develop games, desktop apps, operating systems, browsers, and so on because of its performance. In this article, we will be compiling and executing the C Programming Language codes and also C++ codes with various compilers like CC, GCC, and G++ compilers.

Compile And Run C Code in Linux

Method 1: Using CC Compiler

In this method, we will be compiling and executing the C program code using CC Compiler.

Step 1: First, we need to open the text editor and terminal for writing code and executing it through the terminal.

Step 2: In the text editor we need to write any code using a C programming language .

Example Script:

C

printf ( "welcome to geeks for geeks" );

We have written a simple C program to print the “ welcome to geeks for geeks ” message.

Step 3: Now, we need to save the file with the .c extension. So in this example, we have saved the file as welcome.c.

389

Step 4 : Now compile and run the C code in the terminal using the commands below.

ls cc welcome.c ./a.out

cc Compiler

Our written code has been executed and the output is displayed in the above screenshot.

Method 2: Using GCC Compiler

We can also compile and execute the script using the GCC compiler. So, let’s understand the compilation and execution using GCC example below.

Example Script :

C

int a=10,b=20,c; printf ( "addition of=%d\n" ,c);

Step 1: Navigate to the directory where the file is been saved. Use the below commands.

In this example we are already in the current directory.

Step 2 : Execute the command below for compilation and execution.

cc -o add add.c ./add

GCC compiler

In the above image, we have written a simple C program for the addition of two numbers.

Compile And Run C++ Code in Linux

In this method, we will be compiling and executing the C++ program code using G++ Compiler.

Step 1 : Write the C++ program code in a text file using a text editor and save the file with the .cpp extension.

Example Script:

C++

using namespace std; cout << "Welcome To Geeks For Geeks For Geeks" ;

Step 2: Navigate to the directory where the file is saved.

In this example we are already in the current directory.

Step 3 : Execute the command below for compilation and execution.

g++ cplus.cpp ./a.out

g++ compiler

In the above image, we have written a simple C++ program to print the “ Welcome to GeeksforGeeks ” message.

Conclusion

In this article we discussed how we can compile and run C and C++ programs in Linux using various compilers. C is designed for system programming and kernel development, while C++ excels in performance for games and applications. The methods demonstrated with CC, GCC, and G++ compilers equipped readers to compile and execute code efficiently. We discussed step-by-step instructions and example scripts. Overall, we can say that this article will help programmers to successfully run their C and C++ programs on Linux systems.
