C++ Performance: Lambda vs Function Pointers

What are the performance differences between lambda functions and function pointers in C++?

Lambda functions in C++ can be more efficient than function pointers because they can capture variables and optimize in-line.

Can you explain how capturing variables in lambdas affects performance?

When a lambda captures variables, it can access them directly, reducing the overhead of passing them as parameters, which can enhance performance.

Are there any scenarios where function pointers might be preferred over lambdas?

Yes, function pointers can be simpler in cases where you need to pass a function as a callback without capturing state.

What about readability and maintainability? How do they compare?

Lambdas often improve readability by keeping related code together, while function pointers can lead to more fragmented code.
