Starting C in Ubuntu

First we have to set up c environment in ubuntu

gcc and other neccessary compilers are not pre-installed in Ubuntu.
Execute this

Code:

sudo apt-get update
sudo apt-get install build-essential

In case your machine doesn’t have internet access, execute this first :

Code:

sudo apt-cdrom add

After setting up environment now time to coding. Simply we can create any file as like as test.c. We can open this file in VI editor. And writing some c code like as

#include
int main()
{
   printf("It's me\n");
   return 0;
}

Then save and quit from VI editor. Execute following command to compile and run the test.c file
To compile

gcc test.c

And run

./a.out

That’s it.
