How to Write, Compile and Run a C/C++ Program in Fedora Terminal

---

In this tutorial we will see how to how to write, compile and run a C or C++ program in fedora terminal itself i.e writing, compiling and execution of the program will be done within the terminal itself.

For writing any program we need a console (terminal) based text editor. I 'll be using vim editor, there are many more like nano, jed, emacs...


1. Open up the terminal and install vim by entering the following commands.

dnf -y update

dnf -y install vim-enhanced

2. Install necessary development tools (if not installed already). This includes the compiler.

dnf group install 'Development Tools'

3. Create a new C/C++ program with this vim command.

for C program

vi example.c

for C++ program

vi example.cpp

4. Press the i key or the insert key to start writing the program. After you have completed the program save and exit vim by typing :wq

example programs:
#include<stdio.h> int main() {    printf("Hello World\n");   printf("Welcome to Tech Infected\n") return 0; }     
#include<iostream> using namespace std; int main() { cout<<"Hello World\n"; cout<<"Welcome to Tech Infected\n"; return 0; }

5.Compile the program with the following gcc command. this will create a object file, a.out which will will execute in the next step.

for C program

cc example.c

for C++ program

g++ example.cpp

6. Finally, execute the a.out object file which is created automatically after compiling the program

./a.out

Done!
Output of the above example program.
Hello World Welcome to Tech Infected

To open an existing file use the same command which is used to create a new file
vi example.c
