Problem Statement:

                A 4^th
grader is having trouble with
Permutation
and
Combination
problem in Mathematics, so a friend offered help to create a program they can use. The program contains 3 options, 1^st
option is for Permutation, 2^nd
option is Combination and 3^rd
is for terminating the system. For option 1, Permutation, they uses the following formula: nPr =  ; where r must not be greater than n. It should not proceed if this condition is not met. For 2^nd
option, Combination, they uses the formula : nCr =  ; where r must not be greater than n as well. For the 3^rd
option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates.

Requirements:

1. Develop the required system and use
   cpp
   for the file name


2. Remember that both
   n
   and
   r
   are variables, their values shall only be entered at run time.


3. The program requires the use of any
   looping
   


4. The program requires the use of any
   conditional
   


5. Introduce at least
   2 return type programmer defined functions and 1 void type programmer defined function.


6. Create a
   header file
   containing only the programmer-defined functions you created.
