Help with Plinko please

This code is from my main function. In a nutshell, I want the function multchip_slot to evaluate for the integers 0 - 8.

However, I don't know how to get the function to evaluate for different values without duplicating the function for each new input.

Although the way I've done executes without errors, I feel there must be a simpler way to do it.

Do you know a way that I can have my function evaluate for values 0-8 inclusive without having to rewrite the function?

int main()
		{
 			cout << "Enter a number of chips: ";
 			double num_chips;
			cin >> num_chips; // if user enters 5, drop 5 chips to every slot between 0 - 8
 			double num_chip_saver = num_chips; // preserves the initial entered value of chips to be used as a divisor in computing average chips
			
			
			double a = multchip_slot(num_chips, 0);
			double b = multchip_slot(num_chips, 1);
			double c = multchip_slot(num_chips, 2);
			double d = multchip_slot(num_chips, 3);
			double e = multchip_slot(num_chips, 4);
			double f = multchip_slot(num_chips, 5);
			double g = multchip_slot(num_chips, 6);
			double h = multchip_slot(num_chips, 7);
			double i = multchip_slot(num_chips, 8);

			double j = a + b + c + d + e + f + g + h + i; // sums the total points earned from each of the slots
			cout << "Total points: " << j << endl;
			cout << "Average points: " << j / num_chip_saver << endl; // computes the average points earned per drop

			

Additional info: The function returns "Total Points." My assignment is to create a program that enables users to drop multiple chips into all nine slots of a Plinko board simultaneously. In other words, if a user enters "5" as their number of chips (num_chips) value, it drops 5 chips into each of the nine slots, labeled 0-8. My assignment is to compute the total and average points earned from this.

One word for you.... Loop.

Let's use a container to store all the points values and use a loop to load it up.

Starting off simple, we'll use an array.

const int NUM_TURNS = 8;

double pointsArray[NUM_TURNS];

for (int i = 0; i < NUM_TURNS; i++)
    pointsArray[i] = multchip_slot(num_chips, i);

This should in theory, give you an array containing all the points values.

To get their sum you need to once again, use a loop.

double totalPoints = 0;

for (int i = 0; i < NUM_TURNS; i++)
    totalPoints = pointsArray[i];

If you want to save the extra loop you can add the sum while you load up the container.

Hope this helps.

Thanks so much! Great answer.
