C++11: Standard Lambda vs Function

What are the main differences between C++11 standard lambda expressions and regular functions?

C++11 standard lambda expressions allow for inline function definitions, capturing variables, and are often more concise than regular functions.

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

Sure! Here's a simple example: auto add = [](int a, int b) { return a + b; }; This defines a lambda that adds two integers.

When should I use a lambda instead of a regular function?

Use lambdas for short, temporary functions, especially when passing them as arguments to algorithms or when capturing local variables.

Are there any performance differences between using lambdas and functions?

In general, lambdas can be more efficient due to their ability to capture context and avoid function call overhead in certain scenarios.
