C. In permutations and combinations, the term "n Cr" 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 rat 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.

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.
