Simple example of function

Hello and Asalam o Alikum.

I have shifted to dev C++ compiler.So, from now onward, the programs of my blog would be written in dev c++ compiler.

Today I am here with the simplest example of function. It is about printing a simple statement in C++ using function.

One concept which is important and I want to mention here is "parameters".

Parameters

Parameters are the values that are provided to a function when the function is called.If there is no parameter, only parenthesis are used.

Below is the source code of that simple example of function which I mentioned above.
