Unit5-01: Functions without Parameters

Learning Outcome

At the end of this lesson, you will be able to:

• B2.3 apply the principle of modularity to design reusable code (e.g., subprograms, classes) in computer programs;

• understand and create your own functions with no parameters

Here is the Problem:

• Create a program called "Temperature Converter" that has a function called farenheit()

• This function lets you enter a temperature in degrees Celsius (as a decimal), and converts and displays the temperature in Farenheit.

• All the functionality needs to be written inside the function and not in  main().

• main() will just call the function farenheit()

• Tf = (9/5)*Tc+32

  • Tc = temperature in degrees Celsius

  • Tf = temperature in Farenheit

• you will still have a main() function, but now it will call another function

• The top-down design should be for the entire program.

• There should be a flowchart for each function.

Activity

• in groups of 2, do the following on the board for today's daily assignment:

  • Top-Down Design

  • Flow Chart

  • Pseudocode

  • Test Cases

Daily Assignment

• complete the Daily Assignment section in Hãpara Workspace for this day

  • if Hãpara is not working, make a copy of this document

  • move it to your IMH-ICS folder for this course

Extra

• recreate the same program in C++
