Question

finding factorial of a number using recursive function. 

c++ program

1) n and r should be parallel arrays and be defined at run time (dynamic array) during the program execution

2) computer nCr for each items in the array n and r 

3) display the result

C. In permutations and combinations, the term "n C r" refers to n combinations taken r at a time. n! nCr = r! (n -r)! Write a recursive function to find the factorial of a number. Use the defined function to compute the term "nCr" for the following scenario: The values of 'n' and 'r' are stored in two parallel arrays of any user defined size. You have to Read the arrays n and r at run time. Compute n Crfor each corresponding terms in the array 'n' and 'r', and display it properly formatted. Also your program should print the current date and time using library functions.
