Step 1. Open terminal.
Step 2. Type command to install gcc or g++ complier:
$ sudo apt-get install build-essential
This will install the necessary C/C++ development libraries for your Ubuntu to create C/C++ programs.
But most Linux distributions already come pre-installed with the gcc compiler
To check gcc version type this command:
$ gcc –version or gcc –v
Step 3. Now go to that folder where you will create C/C++ programs. I am creating my programs in Documents directory. Type these commands:
$ cd Documents/
$ sudo mkdir programs
$ cd programs/
Step 4. Open a file using any editor.
$ sudo gedit test.cpp
Step 5. Add this code in the file:
(i). C++ program code:
#include<iostream>
using namespace std;
int main()
{
cout<<“\n\nHello World,\nWelcome to my blog, CodeWithBilly \n\n”<<endl;
return 0;
}
Step 6. Save the file and exit.
Step 7. Compile the program using any of the following command:
(ii). Compiling C++ program.
$ sudo g++ test.cpp (or)
$ sudo g++ -o test test.cpp
[Note: Make sure you are in the same directory where you have created your program before compiling it.]
Step 8. To run this program type this command:
(ii). For running C++ program
$ ./a.out (If you compiled using first command)
Or
$ ./hello (If you compiled using second command)
It will show output on the terminal.
Try this. All the best!!!
