Lambda Expressions

This example illustrates how to use lambda expressions for concise function definitions.

cppCopy code#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};
    std::for_each(numbers.begin(), numbers.end(), [](int n) {
        std::cout << n * n << " "; // Output: 1 4 9 16 25
    });
    std::cout << std::endl;
    return 0;
}
