Simple Lambda function

In this article, I write a c++ program using lambda.

This lambda function squares the input value.
The lambda is assigned to a variable. By calling this variable twice, the code in the body of the lambda gets executed.

#include <iostream>
using namespace std;

int main()
{
    auto square = [](float x){
        return x*x;
    };  
    cout << "Output 1: " << square(5.10) << endl;
    cout << "Output 2: " << square(6.10) << endl;
    return 0;
}

The output is
