KEY OBJECTIVE

Conquer: To understand the need for conditional statements

Aspire: Create your own conditional statements. 

Previously you have:

Written a program in a sequence

Used the print statement

Used a subroutine

Checked for errors in your code

Fixed common errors in your code

Added inputs to allow the user to respond/

PRIMM

All new programmers use the PRIMM method to learn and create new code. There are 5 key stages. 

1. Predict
2. Run
3. Investigate
4. Modify
5. Make

Task 1 - PREDICT

Adding conditions

We have been taking inputs, storing variables and outputting results to the screen

Now we need to add some conditions.

What will the output be if I enter the number 10?

10 is more than 5

Statement is true

Output 10+5 = 15

What will happen in this program if I enter "sunny" and then "raining"?

10 is more than 5

Statement is true

Output 10+5 = 15

Lets check your prediction

INVESTIGATE and MODIFY

• Add another question
• Ask the user how they are feeling
• If the user enters happy give a positive message.
• If they enter unhappy give a hopeful message.

Conditional statements

If statements allow the program to give different responses to user inputs.

1. Grammar
2. Debugging
3. Syntax
4. Functions

What keyword do we use to create a function?

CORRECT

CAUSE AN ERROR

print = ("Hello")

Print("Yes!")

print("this one)

name = imput("what is your name")

name = input("what is your name")

print("this text")

fav colour = "Green"

age = 10

print("Hello", name)

print("Bye",name")
