// Purpose - to illustrate the use of void functions (functions that do not return a value). 
//			One void function has a parameter and the other does not.

#include <iostream>
using namespace std;

void printMyName(int numOfTimes);		// prints the user's name
void printSchoolName();				// prints the name of the user's school

// notice that semicolons are necessary at the end of function
// prototypes statements. Both of the functions are "void functions"
// since they do not "return" values to the function that calls them.

int main()
{          
	int userInput = 0;              // user's inputted number

	cout << "Enter an integer: ";
	cin >> userInput;

	printMyName(userInput);

	// The statement above is a "call statement". It simply calls
	// the function PrintMyName which was declared with a function
	// prototype at the top of the program. When C++ encounters this
	// call statement, it transfers execution control to the function
	// where it is defined at the bottom of the program. The variable
	// UserInput is sent as an argument.

	printSchoolName();

	// This is another call statement that calls the function PrintSchoolName.
	// No argument is sent since none is specified in the parentheses.
	
	return 0;
} // end of main

void printMyName(int numOfTimes)
// this function prints "Mr. Minich" a specified number of times
{

	for (int i = 1; i <= numOfTimes; i++)
	{  
		cout << "Mr. Minich" << endl;  
	}

} // end of printMyName

void printSchoolName()
// this function prints "Penn State University"
{
	cout << "Penn State University" << endl;
} // end of printSchoolName
