CISC105 Spring 2006 Lab04

• Write a program for each of the following problems. Be sure to save every separate program. All programs must be properly commented and indented (see Assignment Standards on the class website).
  
  
• Back up your files! Do you ever really read this stuff? Or am I just writing to the wind? Sometimes important information is here. Actually, it is all important to your success in the course. The sample midterm questions are in the resources directory of the class website.
  
  
• Before you get to lab, read through the practice exam questions so you can ask your TA about anything you are unsure of.
  
  
• Name each program lab04.n.c, where n is the number in the list below. For example, the name of the file for the first will be lab04.1.c. Put the files in your lab04 directory.
  
  

Programs

1. Write a program that has all three components needed for function use that we discussed in class. (Can you name them?) The function should simply print "hello world". There should not be any printing done directly from main.
   
   
2. Copy part 1 and add a loop in main to call the function three times. (Which kind of loop would be appropriate?)
   
   
3. Use a shell command to copy the previous program. Place a loop around the function call in main so that the function is called once each time a number is entered until the user enters a sentinel of -1.
   
   
4. Write a new function that asks the user for a number and prints it out once. Call that function from main.
