Programming Exercises - Variables and Calculations

Page history last edited by Steve Sweeney 5 years ago

 

  1. Write a program that asks the user for three numbers and then outputs the sum (total) of the three numbers.  Are brackets required in the calculation?

  2. Write a program that asks the user for three decimal numbers and then outputs the average of the three numbers.  Warning: Use brackets for order of operations!

  3. Write a program that asks the user to input marks for 4 courses, and the displays the average mark.  Warning: Use brackets for order of operations!

  4. Using the available help or online resources for your programming language, investigate how to do #2 and #3 with your answer rounded to one decimal place.

  5. Have the user enter two integers between 1 and 9. Do the basic math operations using these numbers and display the answer (add, subtract, multiply, divide, exponent).  For example, if the user entered the numbers 2 and 3, you would output the results of 2+3, 2-3, 2*3, 2/3 and 2^3 (2 to the exponent 3).

  6. Ask 5 simple math problems. After the user enters their answer, display the problem and the correct answer. The correct answer should be calculated by your program. 
    Extend: Research random numbers for a way to make your program much more interesting. [Turing Code]

  7. Ask the user their name, age, and the current year. Greet the user and tell them the year they were born.
    Extend: Calculate and tell them the year they will be 25, 50, and 75.

  8. Write a program that will ask the user for the radius of a circle.  The program will then calculate the circumference and area of the circle and output the results clearly.  Use a variable for words marked in bold.

  9. Write a program that will ask the user for the length and width of a rectangle.  The program will then calculate the perimeter and area and output the results clearly.  Use variables for the words marked in bold.
