stl sort in c++

sort c++

#include <algorithm>    // std::sort

int myints[] = {32,71,12,45,26,80,53,33};
// using default comparison (operator <):

// fun returns some form of a<b

sort c++

sort(arr, arr+length); //increase
sort(arr, arr+length, greater<int>()); //decrease 

sort c++

#include <algorithm>    // std::sort

std::vector<int> vec = {1,3,2}; // vec = [1, 3, 2]

stl sort in c++

sort(arr, arr+n, greater<int>()); // sorts in descending order

c++ sort

std::vector s = {5, 1, 3, 6, 2,};

c++ sort code
