Program Plan Intro

Compute the value of “C(n, r)” using iterative version

Program plan:

  • Include required header file.
  • Declare the function for compute factorial of “n”.
  • Define main function.
    • Declare variable for “n” and “r”.
    • Declare a “double” variable for “Cvalue”.
    • Create prompt statement for “n” and “r”.
    • Read the value of “n” and “r” from user.
    • Compute the value of “Cvalue” using the given formula by calling the function “computeFactorial”.
    • Display the result for number of ways for selecting from given “n”.
  • Define “computeFactorial” function with argument “n”.
    • Initializes the value of factorial result to “1”.
    • Using “for” loop, compute the value of factorial.
    • Finally result the factorial result.
