Study Notes
Coding Activities for Classes VII & VIII
- Activity 3: If Conditional Statement involves writing an algorithm, flowchart, and program to make a beaver blend strawberries and serve them to a customer.
- The steps involved are:
- Wait for the customer to arrive
- If the customer arrives, add strawberries
- Blend and serve
- Repeat the process until the last customer arrives
If-else Conditional Statement
- Activity 4 involves writing an algorithm, flowchart, and program to make a beaver blend blackberries and serve them to a duck customer, or blend strawberries and serve them to other customers.
- The steps involved are:
- Wait for the customer to arrive
- If the customer is a duck, add blackberries
- Else, add strawberries
- Blend and serve
- Repeat the process until the last customer arrives
Loops
- Activity 5 involves writing an algorithm, flowchart, and program to make a rat pick matchsticks and add them to a pile.
- Loops are used to automate repetitive tasks.
- Types of loops:
- For loop: used to iterate over a sequence or iterable objects
- Nested for loop: a loop within another loop
- While loop: used to repeatedly execute a block of code while a condition is true
- Nested while loop: a loop structure with another while loop inside it
Variables and Data Types
- Task 2 involves writing an algorithm, flowchart, and program to help a baby monkey get a banana.
- The task involves understanding different data types:
- Integer: a whole number (e.g. 4)
- Floating-point number: a decimal number (e.g. 4.5)
- String: a sequence of characters (e.g. "Welcome")
- Boolean: a true or false value (e.g. False)
Comments
- Comments are used to add descriptions to the code to make it easier to understand.
- Types of comments:
- Single-line comments: marked using the hash (#) symbol at the beginning of a line
- Inline comments: single-line comments written next to the code on the same line
- Multiline comments: used to write multiple lines of description, marked using triple quotes
Input and Output
- Task 1 involves writing a program to implement different scenarios using input and output coding concepts.
- The scenarios involve:
- Assigning a value to a variable and printing a message based on the value
- Using nested-if statements to implement multiple scenarios
Coding Concepts
- Loops are used to automate repetitive tasks.
- There are different types of loops: for loop, nested for loop, while loop, and nested while loop.
- Loops are used to perform operations that require multiple levels of iteration.
Create an algorithm, flowchart, and program to make a beaver blend strawberry and serve it to a customer using if conditional statements.
