Instructions

For this final exam, you may use the text, your notes, programs you have written, as well as PowerPoint slideshows used in class. However, this exam is designed to test your individual knowledge of the course material; Collaboration is not allowed.

You will be creating 2 programs and flow-chart for each using different constructs, functions, and data manipulation.

For each program, include the following information at the top of your code:

Brief statement telling the purpose of the program

Final Exam – CIS126 Program 1
Calculate the hypotenuse of a right triangle

For all programs, brief comments are required as follows:

• All preprocessor directives
• All function prototypes
• All variables and arrays prototypes when defined
• Description of the output from printf()

Program #1

Create a program to calculate the hypotenuse of a right triangle. The values for the sides of the triangle will be input from the keyboard; the hypotenuse will be calculated using the equation c = √(a^2+ b^2 ) where c is the length of the hypotenuse; a and b are the length of the two sides. (c is equal to the square root of the sum of a squared and b squared) (Requires the use of the SQRT() and POW() functions.

Draw the flow chart for the program.

Functional requirements

• Print the header shown above before entering a loop.
• Use a loop to input side a and side b, until side a is -1 (this is similar to the interest program you did earlier)
• Calculate the length of the hypotenuse
  • Values should be output using 3 decimal place precision (hint: %3.3lf)

Program #2

Create a program with three string arrays, two 25-element arrays and one 100 element array.

Functions required:

• Determine string equality
• Display a message indicating the length of the string

Program execution:

• Initialize the arrays in main()
  • Initialize the two 25-element arrays to 0
  • Initialize the 100-element array with: The quick brown fox jumps over the lazy dog.
• Call the function to display the length of the 100-element array; use an appropriate message
• Enter a string into each of the two 25-length arrays
  • Enter strings that match
  • Enter strings that do not match
  • Display the results with the appropriate message about comparing the two strings
• Draw the flow chart for the program.
