  A function is a block of code which only runs when it is called.
  we can pass data  into a function. which is known as parameters,

    Syntax
    void myFunction() {
      // code to be executed
    }
*/

#include <iostream>
using namespace std;

// Function declaration
void myFunction();

// Function declaration
void sayHello();

// Function declaration
void func() ;

// the main Function
int main()
{
    myFunction();    // call the function
    myFunction();    // call the function again
    myFunction();   // call the function again
    myFunction();   // call the function again

    sayHello(); // call the function 

    func();  // call the function
    func();  // call the function
    func(); // call the function

     return 0;// signal to operating system everything works fine

}/** End of main function */


 /**

  I Create a function named my function take
  no parameter print "Hello my name is saddam" */

void myFunction()
{
    // the body of the function (definition)

void func()
{

   int j = 0; //local variables declaration
   i++;  // increment i by one
   j++;  // increment j by one
