Question
Answer in C++, and make it easy for me to copy and paste to recheck work.
The "odd/even factorial" of a positive integer n is represented as n!! and is defined non-recursively as: (n)(n-2)(n-4)...(4)(2) if n is even and is (n)(n-2)(n-4)...(5)(3) (1) if n is odd.
For example 7!! equals 7*5*3*1 or 105 and 6!! equals 6*4*2 or 48.
Come up with a recursive definition for n!! and use it to guide you to write a function definition for a function called oddevenfact that recursively calculates the odd/even factorial value of its single int parameter.
The value returned by oddevenfact is a long.
