How we can make simple non-returning user defined function in c++

It is very easy to know How we can make simple non-returning user defined function in c++. These functions not return the value. There is a lot of use of these functions in c++. Non-returning functions are mostly used in c++. You can watch the code to understand the non-returning user defined functions.

Simple Structure:

dataTypeName  FunctionName ()
{

}

Code without Prototype:

#include <iostream>

using namespace std;

void Fun()

{

                cout<<"How are you."<<endl;

                cout<<"I am fine. ";

}

int main()

{

                Fun();

}

Output:

How are you.

I am fine.

Code with Prototype:

#include <iostream>

using namespace std;

void Fun();

int main()

{

                Fun();

}

void Fun()

{

                cout<<"How are you."<<endl;

                cout<<"I am fine. ";

}

Output:

How are you.

I am fine.

Hope you understand the non-returning user defined functions in c++.
