Extracted text: Write a C++ program to compute the nCr In permutations and combinations, the term nCr 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 nCr for each corresponding terms in the array "n" and "r", store it in another separate array and display the output array properly formatted. • Also your program should print the current date and time using library functions. Sample input: Index Array 'n' 22 13 4. Array T 3 Computed nCr 1540 1287 1 2 2. 6. 3 16 560 100947 18564 23 18 15 18 22 6. 6. 7 8 9. 4. 1364 816 26334 5.
