Take some additional notes that you would like here for 3.12 and 3.13. We will be looking for additional notes from the presentation.

My Notes:

  • A procedure call interrupts a series of statements and makes the program execute the statements in the procedure.
  • After executing, it will return to the original call and finish the statements.
  • In order to determine what the result of a procedure is, you need to carefully examine the code line by line
  • A procedure MAY or MAY NOT return a value (a number or boolean (true or false)).
  • Before we start writing the procedure, we need to know what arguments the procedures require and and what type of data the procedure will return.
  • We need to be able to call the procedure.
  • To call a procedure you would write the name of the procedure followed by the parentheses with the parameters of the procedure (there may not be parameters, but parenthesis must be there).
  • A procedure is a named block of code that performs a specific task, but does not return a value. The procedure can be called by another part of the program. A procedure for a login menu could be written like this: Pseudocode. Python.

What are procedures?

Fill in the blanks please:

Procedure:

  • A Procedure is a named group of programming instructions that may have parameters and return values.

Parameters:

  • Parameters are input values of a procedure. Arguments:
  • Arguments specify the values of the parameters when a procedure is called Modularity:

Procedural Abstraction:

What are some other names for procedures?:

  • Procedures can also be referred as method or function, depending on the language

Why are procedures effective?:

Challenge 1 below: Add the command that will call the procedure. 

n = int(input("Please input a number"))
def convertToBinary(n):
    return (bin(n)[2:])

convertToBinary(n)

'101101'

Challenge 2 below: Complete the Min and Max procedure in either JavaScript and Python using the instructions from the JavaScript page. (JavaScript will get you a extra 0.1) 

numA  = int(input("Please inout a number:"))
numB  = int(input("Please inout a number:"))

def findmax(numA,numB):
    if numA > numB:
        print("You inputed the numbers " + str(numA) + " and " + str(numB) + " out of these two numbers" + str(numA) + " is greater than " + str(numB))
    elif numA < numB:
        print("You inputed the numbers " + str(numA) + " and " + str(numB) + " out of these two numbers " + str(numA) +  " is less than " + str(numB))
    else:
        print("Please input a number")

        
findmax(numA,numB)


 

You inputed the numbers 45 and 65 out of these two numbers 45 is less than 65

I did the js version in the other link I provided

Homework/Hacks: For the hw, you have two options, easy or hard. The easy hack is for a 2.7 + extra work for the full 3. The easy hack is simply creating your own procedure with your own creativity. Since there is a lot of leeway for this one, you must do additional work to get a 3. For the hard hack, below is the start to a character to binary convertor. This is just a template, but the goal is to translate "APCSP" into binary. You can delete the existing code if you want. The only contraint is that you must use a procedure. Doing this will get you a 3. 

text = "APCSP"

def charToBinary(text):
    binary = [convertToBinary(ord(c)) for c in list(text)]
    return binary

print(charToBinary(text))

['1000001', '1010000', '1000011', '1010011', '1010000']
