C++ Lambdas

 C++ Lambdas

Lambdas are anonymous functions in C++ that can be defined inline. They are particularly useful in scenarios where you need to pass a small piece of code as an argument to another function or algorithm. Here's an example:

#include <iostream>

int main() {

    int x = 5;

    int y = 10;

    // Lambda function

    auto sum = [](int a, int b) {

        return a + b;

    };

    int result = sum(x, y);

    std::cout << "Sum: " << result << std::endl;

    return 0;

}

In the above code, we define a lambda function sum that takes two integer arguments and returns their sum. We then invoke the lambda by passing x and y as arguments, storing the result in the result variable. Finally, we print the result.
