Using the double variable type, you will create a program that uses two variables to calculate the number of permutations of the potential team arrangements.
The number of permutations of a set of n items taken r at a time is given by the following formula: where n! is the factorial of n and r! is the factorial of r, and (n-r)! is the factorial of the result of n-r. The factorial of a number n can be solved using the following formula:
If there are 18 people in your class and you want to divide the class into programming teams of 3 members , you can compute the number of different teams that can be arranged using this formula ().
Write a C++ program that determines the number of potential team arrangements. You will need to use the double type variable for this computation.
