sort function in c++ stl code example

Example 1: stl for sorting IN C++

// STL IN C++ FOR SORING
#include  
#include  
using namespace std; 
int main() 
{ 
    int arr[] = {1, 5, 8, 9, 6, 7, 3, 4, 2, 0}; 
    int n = sizeof(arr)/sizeof(arr[0]); 
    sort(arr, arr+n);  // ASCENDING SORT
    reverse(arr,arr+n);   //REVERESE ARRAY 
    sort(arr, arr + n, greater());// DESCENDING SORT
  }

Example 2: c++ sort

int arr[]= {2,3,5,6,1,2,3,6,10,100,200,0,-10};
    int n = sizeof(arr)/sizeof(int);  
    sort(arr,arr+n);

    for(int i: arr)
    {
        cout << i << " ";
    }

Example 3: sort c++

// sort algorithm example
#include      // std::cout
#include     // std::sort
#include        // std::vector

bool myfunction (int i,int j) { return (i myvector (myints, myints+8);               // 32 71 12 45 26 80 53 33

  // using default comparison (operator <):
  std::sort (myvector.begin(), myvector.begin()+4);           //(12 32 45 71)26 80 53 33

  // using function as comp
  std::sort (myvector.begin()+4, myvector.end(), myfunction); // 12 32 45 71(26 33 53 80)

  // using object as comp
  std::sort (myvector.begin(), myvector.end(), myobject);     //(12 26 32 33 45 53 71 80)

  // print out content:
  std::cout << "myvector contains:";
  for (std::vector::iterator it=myvector.begin(); it!=myvector.end(); ++it)
    std::cout << ' ' << *it;
  std::cout << '\n';

  return 0;
}
