I remember my encounter with the g++ compiler, it was just before a coding competition. Owing my background to Windows and turboc, it was a good experience to work on linux(Ubuntu) and g++ compiler. The following simple steps show how to write and execute a simple c++ code.
1. Check your g++ installation by typing the following on the terminal:
~$g++
If g++ is installed the following will be the response:
g++: no input files
If not then Ubuntu and Debian users type the following to install:
~$sudo apt-get install g++
2.After checking your compiler open and empty document and name it suppose hello.cpp
3.Type the following using your favorite text editor
#include<iostream>
using namespace std;
int main()
{
cout<<"hello";
return 0;
}
save the file. Make sure you save it in your current working directory.
4. On the terminal type the following:
~$g++ hello.cpp
~$./a.out
and vol la you are done.
