Abstraction

Computer scientists use abstraction to understand and solve problems and communicate their solutions with the computer in some particular computer language.
# data abstraction
{allow user to build data structures from primitive types and able to use them as primitive ones}
# (functional) procedural abstraction

Compile the *.cpp source

in linux systems:

please note you need to have installed (your choice of) compiler.

run this code in your terminal

sudo aptitude update && sudo aptitude install g++

#include 
using namespace std;


int main()
{
	cout << "hello world\n";	
}

save this as file_name.cpp.
from the same folder run:

any_user@host# g++ file_name.cpp -o filename

then run:

any_user@host# ./filename

(Make sure not using gpp as it works for c source.)

output:
