Skill set for this LAB:

• Understand and implement the Program Development Cycle
• Use Simple Functions
• Use Top-Down Design
• Use variables and assignment statements
• Use input and print functions
• Use basic arithmetic operations
• Save, run and submit programs
• Testing programs
• Writing Lab reports

• Python Programming Practice

  In all programs:

  • YOU MUST TO WRITE INFORMATIVE COMMENTS!
  • You MUST use Top-Down Design
  • Each subtask MUST be a separate function
  • You MUST have function MAIN in your program.
  • In this lab you WILL NOT SHOW me the output and the source file. It will be YOUR responsibility to TEST your program
  • Submission: print source file and lab report. You can write lab report in the same file AFTER the program but make sure you start each line with # to indicate comments. You can also write lab repot on the paper.

  Testing and Lab Reports for Each Program must include the following information. Write it in separate file and submit along with the source file

  • Names of ALL functions in your program
  • Names of formal and actual parameteres for EACH function
  • List of input values you used to test your program.
  • For each test input, document the output your program produced. If the output is NOT correct, document the list of action you performed to correct logical errors.

Problem 1 : Write a program that calculates the insurance points that three different people will receive for speeding on highway. The upper speed limit on the highway is 65 mph. You can assume that speed is integer number. Use the following table:

Speeding Points Table

Problem 2 : Highway 1 has only even exit numbers between 2 and 20 inclusive. Highway 2 has only odd exit numbers between 1 and 19 inlusive. Due to the constructions, each highway has different speed limits on various exits defined by the tables below.

Write a program that reads TWO exit numbers and outputs the speed limit for each exit. Pay attention, your program must check if the exit is even or odd and call an appropriate function. Also, if the input is outside of the exit range, your program must print the error message.

For example, if the input is 7, 21. The output will be: 65 mph, invalid input. And if the input is 10, 11. The output will be 55 mph, 50 mph.

Highway 2 Speed Limit Table:

Problem 3 : Write a function aveDigits that finds and prints an average of the digits of the 4-digit positive integer. Write a function average that finds and prints an average of three integer numbers. Write a function aveLast that finds and prints an average of the last digits of three integer numbers. Write a program that first reads 1 integer, if the integer is positive and even, the program reads 3 integers and finds their average. If the number is positive and odd, the program reads 3 integers and finds the average of their last digits, otherwise, the program asks user to enter one 4-digit integer number and finds the average of the digits of the input number.

Lab Assignment will start at 2:50 and ends at 3:30. At 3:30 all students will run their program and then submit it by e-mail. NO LAB REPORT for assignment
