Thread: working with functions

Hello everyone,

I am working with functions now and tryin to understand them.

I have been practicing different ways for using them.

such as below:

Code:

int greetings();                       // this is a prototype 
 
int age();

int main()
{

	int greetings();                   // this is a function header
	{                                  // start of function body

        char name[20];
		cout << "Please enter your name?  ";
		cin >> name;
		cout << "Hello "<< name <<"\n";

	
	}                                  //end of function body


 cout <<"Enter your age? ";


	    int age();            
		
		{                    
    	int age;

	    cin >> age;
		cout << "You are  " << age << " years old\n\n";

		} 
/* Next I would like to use my greetins function again in        
    my program: */

  int greetings();    // :here                    


	return 0;
}

What I would like to learn next is how to use the same functions over in the program.

I would normally use a loop to repeat this code but I want to know how to reuse the functions in the program.
