Modular Programming Thursday, October 07, 2010 10:43 AM 1. Void a. With value parameters b. With reference parameters 2. Value-Returning a. With value parameters b. With reference parameters (not recommended) Function Example Return-type name (list of parameters) { Executable } Void function(); (declares a prototype function) Function(); - runs a function Void displayAnswers(double area, double circ) { Cout<<fixed; Cout << "C is " << setprescision(2)<< circ << endl; } Void functions Void functionname ("list of paramters) { "Body of function" } Program example: Void hello (int count)
