Common Coding Mistakes and How to Avoid Them In this presentation, we'll go over some of the most common coding mistakes and show you how to avoid them. Whether you're a beginner or an experienced programmer, there's always something to learn, so let's get started. by Kritika Ramone
Data Type Errors String and Number Types Boolean Logic Type Conversion Using poor boolean logic can lead to incorrect results. Use well-formed boolean expressions and learn truth tables to avoid data errors. Assigning incompatible types can cause run-time errors. Use type casting to prevent unexpected output and maximize program efficiency. Unmatched data types can cause unexpected errors. Convert input types to prevent errors and improve code quality. Data Validation Invalid user input is common. Validate data inputs using built-in or custom functions to prevent errors and improve program security.
Syntax Errors Misspelled Variables Misspelling a variable can cause syntax errors. Spell variables correctly to avoid run-time errors. 1 2 3 Missing Semicolons Not Indentation Missing a semicolon can cause syntax errors. Use semicolons in the correct places to improve code quality. Not indenting code can make it hard to read and cause syntax errors. Indent code to make it more readable and catch syntax errors faster.
Logic Errors Unexpected Output Incorrect Output Use debugging tools to identify logic errors. Use flowcharts to help you design and plan your program to avoid these errors in the first place. Code that does not produce the correct output. Use algorithms to break down complex problems and simplify them, and pair programming to identify multiple possible solutions.
Code Redundancy Repeated Code Long Functions Unnecessary Comments Repeated code can be a sign of poor programming practices. Consolidate repeated code blocks into one reusable function. Long functions can be hard to read and maintain. Break up long functions into smaller reusable units and test them separately. Comments can become irrelevant or misleading over time. Comment only where necessary and use self-documenting code.
Poor Debugging Practices 1 Debugging with Print Using print statements for debugging can be time-consuming. Use debugging tools like breakpoints and step-through to debug more efficiently. 2 Debugging Late Debugging errors too late can lead to more errors. Debug code regularly and keep your code well-documented. 3 Not Tracking Changes Not tracking your code changes can cause headaches when bugs pop up. Use version control and commit regularly to keep track of the changes.
