whats a lambda

// C++ program to demonstrate lambda expression in C++
#include <bits/stdc++.h>
using namespace std;
  
// Function to print vector
void printVector(vector<int> v)
{
    // lambda expression to print vector
    for_each(v.begin(), v.end(), [](int i)
    {
        std::cout << i << " ";
    });
    cout << endl;
}
  
int main()
{
    vector<int> v {4, 1, 3, 5, 2, 3, 1, 7};
  
    printVector(v);
  
    // below snippet find first number greater than 4
    // find_if searches for an element for which
    // function(third argument) returns true
    vector<int>:: iterator p = find_if(v.begin(), v.end(), [](int i)
    {
        return i > 4;
    });
    cout << "First number greater than 4 is : " << *p << endl;
  
  
    // function to sort vector, lambda expression is for sorting in
    // non-decreasing order Compiler can make out return type as
    // bool, but shown here just for explanation
    sort(v.begin(), v.end(), [](const int& a, const int& b) -> bool
    {
        return a > b;
    });
  
    printVector(v);
  
    // function to count numbers greater than or equal to 5
    int count_5 = count_if(v.begin(), v.end(), [](int a)
    {
        return (a >= 5);
    });
    cout << "The number of elements greater than or equal to 5 is : "
         << count_5 << endl;
  
    // function for removing duplicate element (after sorting all
    // duplicate comes together)
    p = unique(v.begin(), v.end(), [](int a, int b)
    {
        return a == b;
    });
  
    // resizing vector to make size equal to total different number
    v.resize(distance(v.begin(), p));
    printVector(v);
  
    // accumulate function accumulate the container on the basis of
    // function provided as third argument
    int arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    int f = accumulate(arr, arr + 10, 1, [](int i, int j)
    {
        return i * j;
    });
  
    cout << "Factorial of 10 is : " << f << endl;
  
    //     We can also access function by storing this into variable
    auto square = [](int i)
    {
        return i * i;
    };
  
    cout << "Square of 5 is : " << square(5) << endl;
}

With which of the following can you run code without provisioning or managing servers and pay only for the compute time consumed (there is no charge when the code is not running)?

AWS Lambda lets you run code without provisioning or managing servers

why aws lambda is called lambda

In programming, a Lambda expression (or function) is just an anonymous function, i.e., a function with no name.
