Transcribed Image Text:### Flowchart: Random Number Generation and Display
#### Description:
This flowchart outlines a simple algorithm to generate a random number between 1 and 10 and displays a value based on the number generated.
#### Steps Explained:
1. **Start**: The algorithm begins at the "Start" oval.
2. **Generate Random Number**:
- Action Box: `myNum ← RANDOM(1,10)`
- The system generates a random number, `myNum`, between 1 and 10.
3. **Decision Node (Check Number)**:
- Diamond Shape: `myNum > 8`
- The algorithm checks if the generated number `myNum` is greater than 8.
4. **Condition - True**:
- If `myNum` is greater than 8:
- Action Box: `DISPLAY("Done")`
- The system outputs the message "Done".
5. **Condition - False**:
- If `myNum` is not greater than 8:
- Action Box: `DISPLAY(myNum)`
- The system outputs the value of `myNum`.
#### Diagram Interpretation:
- **Start Node**: Represented by an oval.
- **Action Nodes**: Denoted by rectangular boxes containing actions such as generating a random number and displaying a message or number.
- **Decision Node**: Shown as a diamond shape where a condition is checked.
- **Flow Lines**: Arrows that indicate the direction of flow from one step to the next. There are two branches from the decision node—one for "true" and another for "false".
This flowchart visually demonstrates a basic conditional setup where a random number guides the message to be displayed based on a simple numerical comparison. This type of flowchart can be useful for illustrating basic programming logic or algorithm design for educational purposes.

### Exploring Conditional Statements and Repetition Structures in Programming
Below are four different code snippets that demonstrate the use of conditional statements (IF/ELSE) and repetition structures (REPEAT UNTIL) in programming. Each snippet showcases different logical flows and decision-making processes.
#### Code Snippet 1
```plaintext
myNum ← RANDOM(1, 10)
IF (myNum > 8)
{
DISPLAY("Done")
}
ELSE
{
DISPLAY(myNum)
}
```
**Explanation:**
- A random number between 1 and 10 is assigned to the variable `myNum`.
- If `myNum` is greater than 8, the message "Done" is displayed.
- Otherwise, the value of `myNum` is displayed.
#### Code Snippet 2
```plaintext
myNum ← RANDOM(1, 10)
REPEAT UNTIL (myNum > 8)
{
DISPLAY(myNum)
myNum ← RANDOM(1, 10)
}
DISPLAY("Done")
```
**Explanation:**
- A random number between 1 and 10 is assigned to the variable `myNum`.
- The code then enters a loop that repeats until `myNum` is greater than 8.
- Inside the loop, the current value of `myNum` is displayed, and a new random number is assigned to `myNum`.
- Once `myNum` is greater than 8, the loop terminates, and the message "Done" is displayed.
#### Code Snippet 3
```plaintext
myNum ← RANDOM(1, 10)
IF (myNum < 8)
{
DISPLAY("Done")
}
ELSE
{
DISPLAY(myNum)
}
```
**Explanation:**
- A random number between 1 and 10 is assigned to the variable `myNum`.
- If `myNum` is less than 8, the message "Done" is displayed.
- Otherwise, the value of `myNum` is displayed.
#### Code Snippet 4
```plaintext
myNum ← RANDOM(1, 10)
REPEAT UNTIL (myNum ≥ 8)
{
DISPLAY("Done")
}
DISPLAY(myNum)
```
**Explanation:**
- A random number between 1 and 10 is assigned to the variable `myNum`.
- The code then enters a
