Labs

These labs are designed to use a switch statement.

  1. Write a program that asks for a temperature and scale. Use a switch statement and take advantage of fall through.

  2. If the scale is C, c, Celsius, or celsius, convert the number from Celsius to Fahrenheit with the formula Fahrenheit = (9.0/5.0 Celsius) + 32.

  3. If the scale is F, f, Fahrenheit, or fahrenheit, convert the number from Fahrenheit to Celsius with the formula Celsius = 5.0/9.0 (Fahrenheit - 32).
  4. Depending on the scale, the output should look like 32 degrees Fahrenheit is 0 degrees Celsius.
  5. If the scale is invalid, print an error message.

  1. Write a simple calculater program.

  2. Ask the user to enter two numbers, reading them into two double variables.

  3. Ask the user to enter an operation: +, -, *, /, or %.
  4. Use a switch to determine which operation they entered, and output the correct result.
  5. If an invalid operation is entered, output "Operation not valid".
  6. Use fall-through to allow a variety of valid input for each operation, such as *, times, multiply, etc., calculating the result in only one place for each type of operation.
