Runtime error handling in Compiler Design - Mini Project: Build & Apply

Understanding Runtime Error Handling

📋 What You'll Learn

💡 Why This Matters

🌍 Real World

Runtime error handling is used in all software to prevent crashes and provide meaningful responses when unexpected problems happen during execution.

💼 Career

Understanding runtime error handling is essential for software developers, testers, and system engineers to build reliable and user-friendly applications.

1

Define Common Runtime Errors

Create a list called runtime_errors containing these exact strings: 'DivisionByZero', 'FileNotFound', 'NullReference', 'IndexOutOfRange'.

Compiler Design

# Your code here

Need a hint?

Use a list with the exact error names as strings inside square brackets.

2

Set Up Error Tracking Variable

Create a variable called error_occurred and set it to False to track if a runtime error happens.

Compiler Design

runtime_errors = ['DivisionByZero', 'FileNotFound', 'NullReference', 'IndexOutOfRange']
# Your code here

Need a hint?

Use a boolean variable set to False initially.

3

Detect a Division By Zero Error

Write an if statement that checks if the string 'DivisionByZero' is in runtime_errors. If it is, set error_occurred to True.

Compiler Design

runtime_errors = ['DivisionByZero', 'FileNotFound', 'NullReference', 'IndexOutOfRange']
error_occurred = False
# Your code here

Need a hint?

Use an if statement with the in keyword to check membership.

4

Handle the Error and Continue

Add an if statement that checks if error_occurred is True. Inside it, add a comment line # Handle the error here to keep the program running.

Compiler Design

runtime_errors = ['DivisionByZero', 'FileNotFound', 'NullReference', 'IndexOutOfRange']
error_occurred = False
if 'DivisionByZero' in runtime_errors:
    error_occurred = True
# Your code here

Need a hint?

Use an if statement to check the boolean and add a comment inside.
