How to run c++ code/program in linux terminal

It is easy to compile and run a c++ program in terminal ( i am using ubuntu 18.4). Since you have come this far, I am assuming you have the basic knowledge creating a file and saving it in the Linux directory.
Rest steps to compile and run are mentioned below.

If you are just looking for the commands here they are
1.) g++ FILE_NAME.cpp -o OUTPUT_NAME
2.) ./OUTPUT_NAME

Lets take a simple example of c++ code.

#include<iostream>
#include<math.h>
#include<time.h>
#include<string.h>
#include<algorithm>
#include<stdio.h>
#include<stdlib.h>

using namespace std;

int main(){
cout<<"I AM AWESOME"; // "Hello Word" is way too main stream
return 0;
}

Saved as filename “example.cpp” at path “/bitsofjarvis/c++/example.cpp“.
I am in my home directory i.e “/home”.

Step 1: Make sure gcc or  g++ compiler is installed. check the version by "gcc --version" or Use the below command to install.
sudo apt-get install build-essential

Step 2: Compile the code and create another executable binary file (by the name provided). Command is
g++ FILE_NAME.cpp -o OUTPUT_NAME
Here in our example, it would be
g++ /bitsofjarvis/algorith/example.cpp -o /bitsofjarvis/algorith/example_executable
One can see then a star marked file with name “*example_executable” would have been created.

step 3: Run the executable file to get the output of the code.
./PATH_TO_EXECUTABLE_FILE
./bitsofjarvis/algorith/example_executable

That’s it you can see the output on the terminal :

I AM AWESOME

Please comment below, if I have missed anything or you need more clarity on any part. I woud be happy to answer it.

Happy Coding !!!!!
