Chapter 14, Problem 3PP

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.
