Jordan University of Science and Technology CS102 Introduction to programming lab Summer Semester 2010-2011 Lab#9: Function II Assignment #1 (20 minutes) Write a program that declares two double variables and input their values by using a void function READ that takes two reference parameters. Send them to the function MULTIPLY that takes two double parameters and return a double of their product()حاصل ضرب العددين. Send the value of their product to the void function PRINT to print heir values. The Output is as the following: Please insert two numbers : 4.5 2 Their product is 9 Assignment #2 (40 minutes) Write a program that prompts the user to insert a number then calculate the value of this equation n Σ 7x3+2x x=0 by using the following two functions 1- Equation1 : that takes one parameter and return a value 2- Equation2: that takes two parameters and returns nothing EX. Please insert a number: 2 The sum is 69 The sum is 69 Assignment #3 (20 minutes) Write a program that prompts the user to insert a positive integer number then send it to a void function Draw that will print a square of “@” symbols with a diagonal) (قطر المربعof “* “ symbols. EX. Please insert an integer number: 5 $ @@@@ @$ @@@ @@$ @@ @@@$ @ @@@@$
