Question
In a bowling game, there are a total of ten pins arranged in four rows, like this:
*
**
***
****
Note that there's one pin in the first row, two in the second and so on.
Now, suppose that there's a strange alien civilization where they bowl using 8,359 rows of pins. Furthermore, their pins are arranged with one pin in the first row, three in the second and so on.

Write a program that uses a while loop to compute and display how many total pins there would be in such a game.
Explanation / Answer
General function:
int sumPins(int rows)
{
int count, pins = 0;
while(count < rows)
{
pins += 2*count + 1;
count++;
}
return pins;
}
Now you need to just use the function/method in the main method of a program. This function should work for most languages.
