9. Write function definitions for the two functions declared in the following program so that they work as described in the pre- & post-conditions.

#include<iostream>
using namespace std;

void input_values( char& repeat, int& times );
; pre-conditions: none
; post-conditions: first argument holds user response to question
	"do you want to play?"; second argument holds user response to question "how many times?"

bool test_input( char in, int number );
; pre-conditions: first & second arguments are initialized
; post-conditions: function returns true if parameter in contains 'Y' or 'y'
; AND parameter number is greater than 0.

int main()
{
	char yes_or_no;
	int number_of_loops;
	bool go_ahead;

	input_values( yes_or_no, number_of_loops );
	go_ahead = test_input( yes_or_no, number_of_loops );

	if( go_ahead )
	{
		while( number_of_loops > 0 )
		{
			cout << "you asked for this!" << endl;
			number_of_loops = number_of_loops - 1;
		}
}
else
{
	cout << "you declined!" << endl
		<< "you answered " << yes_or_no
		<< " and specified " << number_of_loops
		<< " loops." << endl;
}

return 0;
}


10. What output do you expect from the program if the user inputs 'Y' and -32?
	Test your code MANUALLY to confirm your expectation.



NOTE: questions 9 & 10 will be graded for actual points!!
