C++: Lambda Functions vs. Standard Functions

What are the main differences between lambda functions and standard functions in C++?

Lambda functions are anonymous and can capture variables from their surrounding scope, while standard functions are named and cannot capture variables.

Can you give me an example of a lambda function in C++?

Sure! Here's a simple example: auto add = [](int a, int b) { return a + b; }; You can call it like this: add(2, 3);.

When should I use lambda functions instead of standard functions?

Use lambda functions for short, throwaway functions or when you need to capture local variables. Standard functions are better for reusable code.

Are there any performance differences between the two?

In general, lambda functions can be as efficient as standard functions, but it depends on how they are used and optimized by the compiler.
