What are lambda expressions in C++?
An example of an AI chatbot conversation about C++ lambda expressions syntax.
What are lambda expressions in C++?
Lambda expressions in C++ are a way to create anonymous functions directly in your code. They allow you to define a function inline without needing to formally declare it.
Can you show me the syntax for a simple lambda expression?
Sure! The basic syntax is: [] (parameters) { body }. For example: [ ] (int x, int y) { return x + y; }.
What do the brackets [] mean in the syntax?
The brackets [] are used to capture variables from the surrounding scope. You can specify which variables to capture or use an empty bracket for no capture.
Can lambda expressions be used with STL algorithms?
Yes, lambda expressions are often used with STL algorithms like std::sort, std::for_each, and others to provide custom behavior.
