What are some examples of capturing lambda functions in C++?

Can you explain what capturing lambda functions are in C++?

Capturing lambda functions in C++ allow you to use variables from the surrounding scope within the lambda. This is done using capture clauses.

What are the different ways to capture variables in a lambda?

You can capture variables by value or by reference. By value creates a copy, while by reference allows you to modify the original variable.

Can you give me an example of each type of capture?

Sure! For by value: auto lambda = [x]() { return x + 1; }; and for by reference: auto lambda = [&x]() { x += 1; };.

Are there any limitations to using lambda captures?

Yes, captured variables must outlive the lambda. Also, capturing large objects by value can lead to performance issues.
