Lambdas

Lambdas, also known as lambda expressions, are a concise way to define anonymous functions directly within the code where they are needed. They are essentially nameless functions that can capture variables from the surrounding scope. Lambdas are particularly useful for short, self-contained operations, making code more readable and efficient by eliminating the need to define separate named functions for simple tasks, often used with algorithms like std::sort or std::for_each.
