Question

How to use an anonymous function in C++

Answer 1

// Anonymous function = A function with no identifier.

#include <iostream>

int main() {
    // Anonymous function (lambda) assigned to a variable.
    // This lambda takes two integers and returns their sum.
    auto add = [](int a, int b) {
        return a + b;
    };

    // Use the anonymous function
    int result = add(10, 20);

    std::cout << result << std::endl;
}
