CS201
Lab 7 - Function Parameters

Objectives:

• Calculate the area under a curve using a C program.
• Practice use of for-type loops, switch statements, and enumerated types.

Readings:

• Read Chapter 7 in the Hanly/Koffman text.

Deliverables: (DUE 72 HRS AFTER THE END OF YOUR LAB!)

• Submittal of the following files:
  • Makefile
  • Proto.h
  • Lab7.c
  • Trap.c
  • XSquaredSinX.c
  • HalfCircle.c
  • TestFunction.c

TO DO (for this lab)

• Design and Write a program to solve Programming Project #6 on page 363-364 of the Hanly/Koffman text.
• Carefully choose which parameters need to be passed by reference, and when passing by value is enough... 
• Make sure to use nested (i.e. double)  for-type loop to calculate and print out your results.
• Define enumerated type to reflect your three functions (i.e. xsquaredsinx, halfcircle, testfunction), and use it in the nested loop. Switch-type statement may also prove itself to be helpful. :)
• Make sure that your Makefile is going to properly rebuild the run image.
• You will need to build four separate source files, one include file for prototypes, and a stub for my TestFunction that will be supplied after submittal.
• TestFunction Stub
• Type of function is double.
• Name of function is TestFunction.
• Number of parameters is one.
• Type of parameter is double.
• Your stub will need to be called properly in your main program. The value it returns (can be anything) should be properly formatted as an output statement (see below).
• When we grade your program, we will overwrite your TestFunction.c with our version of TestFunction.c and your program will then produce an expected output that we will check for.
• Inputs: none, the program just runs.
• Outputs: (#'s represents your calculated data):
