CSE 232 Spring 2012

Computer Project #2 -- C++ Programming

Assignment Overview:

  This assignment focuses on the design, implementation and testing of C++
  programs.  You will develop a C++ program for each of the problems below.

  It is worth 30 points (3% of course grade), and must be completed no later
  than 11:59 PM on Thursday, January 26.

Assignment Deliverables:

  The deliverables for this assignment are the following files:

    proj02.problem1.cpp  -- your C++ source code for Problem #1
    proj02.problem2.cpp  -- your C++ source code for Problem #2

  Be sure to use the specified file names, and to submit your files for
  grading via the "handin" system.

Problem #1 Specifications:

  Given the length, width, and height of a rectangular solid, display the
  surface area and the volume of the solid.  Each of the three dimensions will
  be an integer number representing a measurement in inches.

  Input values:

    length of the solid
    width of the solid
    height of the solid

  Output values:

    surface area of the solid
    volume of the solid

  The program will prompt the user to enter each input value (in the order
  specified above).  The program is not required to check any of the input
  values for user errors.  The program must behave in a reasonable manner for
  any input values entered by the user; however, its behavior is only
  specified for positive input values.

  All program output will be appropriately formatted and labeled.

Problem #1 Notes:

  1) The surface area of a rectangular solid equals the sum of the areas of
  the six faces of the solid.

  2) The volume of a rectangular solid equals the product of the length, width
  and height of the solid.

  3) Use the following commands to translate and execute your program:

     <prompt> g++ proj02.problem1.cpp
     <prompt> a.out



Problem #2 Specifications:

  Given the length of all three sides of a triangle, display the measure of
  each of the three interior angles (in both degrees and radians), the
  perimeter of the triangle, and the area of the triangle.  The length of a
  side will be a real number representing a measurement in centimeters.

  Input values:

    length of side A of the triangle
    length of side B of the triangle
    length of side C of the triangle

  Output values:

    measure of the angle between sides A and B (in degrees and radians)
    measure of the angle between sides A and C (in degrees and radians)
    measure of the angle between sides B and C (in degrees and radians)
    perimeter of the triangle
    area of the triangle

  The program will prompt the user to enter each input value (in the order
  specified above).  The program is not required to check any of the input
  values for user errors.  The program must behave in a reasonable manner for
  any input values entered by the user; however, its behavior is only
  specified for positive input values.

  All program output will be appropriately formatted and labeled.  All real
  values will be displayed with two fractional digits.

Problem #2 Notes:

  1) The radian measure of an angle equals the degree measure of the angle
  multiplied by pi and divided by 180.

  2) The square of the length of any side of a triangle equals the sum of the
  squares of the lengths of the other two sides minus twice the product of the
  lengths of the other two sides and the cosine of the angle between them.

  3) The perimeter of a triangle equals the sum of the lengths of the three
  sides of the triangle.

  4) The area of a triangle equals one-half the product of the lengths of any
  two sides and the sine of the angle between them.

  5) Use the following commands to translate and execute your program:

     <prompt> g++ proj02.problem2.cpp
     <prompt> a.out
