Problem Statement: C++ PROGRAM

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:

Develop the required system and use cpp for the file name
Remember that both n and r are variables, their values shall only be entered at run time.
The program requires the use of any looping
The program requires the use of any conditional
Introduce at least 2 return type programmer defined functions and 1 void type programmer defined function.
