help 3 ???

Code:

#include <iostream> /*for cin and cout*/

int main() /*function main*/
{
int num = 0;
float sum= 0;
float avg= 0;
int count = 0;
int largest = 0;
int smallest= 0;
int product = 0;

while (1)				//never ending loop//start loop body
{										
	std::cout <<"Please enter an integer enter (-1 to stop)";
	std::cin >> num;
	   
	if (num == -1)
{		break;							//get out of the loop
}    else;
		sum += num;						//  start else body
		count++;
		avg = (sum)/count;
		
		if (count == 1)
{		smallest = largest = num;
}		else;
										//	 start else body;
			if (num < smallest)
	{	 	smallest = num;
			
				if (num > largest)
				largest = num;
			else;								//end body;
}	else;								//end body;
}										//end loop body;
   	
	product = (smallest * largest); //product = num * num??
		
	std::cout << "The number of the integers is " << count << std::endl;
	std::cout << "The sum of the integers is " << sum << std::endl;
	std::cout << "The average of the integers is " << avg << std::endl;
	std::cout << "The product of the integers is " << product << std::endl;
	std::cout << "The largest integers is " << largest << std::endl;
	std::cout << "The smallest integers is " << smallest << std::endl;

	return 0;
}

this board has been a tremendous amount of help and I have a couple of ???

1) If i enter three intergers into the program say 5 4 2 -1
everything work except my product out put it ends up with 10 instead of say 40, does that statement have to be in the while loop
somewhere???

2) smallest = largest = num; I'm a little confused about this statement if i enter say 5 4 2 is it ending up assigning 2 to num after the program runs???

many thanks to all

because it is the product of largest (5) and smallest (2)
5x2=10

Code:

product = (smallest * largest);

if you want the product of all numbers: then do smthing like this:

Code:

product = 1;

Code:

sum += num;
product *= num;

cool!! still confused about what

Code:

if (count == 1)
	smallest = largest = num;

does???

that assigns the very first input number to smallest and largest

ie: u entered 5 as ur first num
then largest = num, and smallest = largest

what concerns me is....

Code:

while(1)

As far as i have seen in my c+ career.. there has been some sort of condition that will at some point, terminate the loop.

example:

Code:

while (counter < 5)

or something like

Code:

while (choice != 'Q')

I would like to see some sort of variable in your while() loop.. by having only a constant.. i am not sure if your loop will ever terminate.

His loop will terminate with this code:

Code:

if (num == -1)
{
    break;    //get out of the loop
}

break will, as it says, break a loop or switch, so he has a condition where the loop terminates.
