Program to add two constants

After printing a simple "Hello" word.
Now its turn to do little advance....

Before learning this you should be familiar to data types and basic operators used with C language.

Here in this program we are adding two constant values and assigning that value to a variable. And then we are printing that variable using printf() function.
Isn't it simple ?
