Multi-Paradigm Programming with Modern C++ - What Makes a Good Function

The video tutorial discusses the importance of functions in C programming, emphasizing that good functions perform a single logical operation and should be kept small. It highlights the common issue of large functions leading to technical debt and provides strategies for refactoring them into smaller, more manageable pieces. The tutorial also introduces new C features like span and string view, and demonstrates how to organize functions into a class structure. Finally, it offers guidelines for naming functions effectively, stressing the importance of descriptive and consistent naming conventions.

What is a key characteristic of a well-designed function in C programming?

• It performs multiple operations.

• It is as large as possible.

• It uses complex algorithms.

• It performs a single logical operation.

What is a common issue that can occur when functions grow too large?

• They become easier to maintain.

• They accumulate technical debt.

• They execute faster.

• They require fewer resources.

What is one strategy for managing shared data among multiple functions?

• Using global variables.

• Creating a class to encapsulate the data.

• Using a single large function.

• Storing data in a file.

What should a function name ideally describe?

• The number of lines in the function.

• The complexity of the function.

• The one thing the function does.

• The author of the function.

What is the recommended approach when a function performs two tasks?

• Combine the tasks into one function.

• Use a random name for the function.

• Reflect both tasks in the function name.

• Ignore one of the tasks.

What type of functions should have a verb in their name?

• Functions that perform queries.

• Functions that perform commands.

• Functions that are very small.

• Functions that are very large.

What is a possible exception to the rule that query functions do not need a verb in their name?

• Functions that are rarely used.

• Getters, which can be prefixed with 'get'.

• Functions that are part of a library.

• Functions that are very complex.
