Type checking rules ensure that variables are used consistently across your programs. Statically typed languages (e.g., Java, C++) require variable types to be defined at compile time, preventing type errors before execution. Dynamically typed languages (e.g., Python, JavaScript) perform type checking at runtime, allowing more flexibility but also potential runtime errors. To avoid issues, always ensure variables are used according to their specified type and leverage development tools like linters for early detection.

FAQs & Answers

  1. What is type checking in programming? Type checking is the process of verifying the type of a variable in program code to prevent type errors during execution.
  2. What are statically typed languages? Statically typed languages require variable types to be defined at compile time, such as Java and C++.
  3. What are dynamically typed languages? Dynamically typed languages perform type checking at runtime, which allows for more flexible coding but can lead to runtime errors.
  4. How can I prevent type errors in my code? Use linters and type checkers as development tools to catch type-related issues early in the coding process.
