Check out example codes for "sort in c++". It will help you in understanding the concepts better.

Code Example 1

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 << " ";
    }

Code Example 2

sort(arr, arr+n); 
sort(arr, arr+n, greater<int>()); // In Descending Order

Code Example 3

// C++ program to demonstrate default behaviour of 
// sort() in STL. 
#include <bits/stdc++.h> 
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); 
  
    cout << "\nArray after sorting using "
         "default sort is : \n"; 
    for (int i = 0; i < n; ++i) 
        cout << arr[i] << " "; 
  
    return 0; 
}

Code Example 4

// C++ program to demonstrate default behaviour of 
// sort() in STL. 
#include <bits/stdc++.h> 
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); 
  
    cout << "\nArray after sorting using "
         "default sort is : \n"; 
    for (int i = 0; i < n; ++i) 
        cout << arr[i] << " "; 
  
    return 0; 
}

Code Example 5

#include <bits/stdc++.h>
using namespace std;

int main()
{
    ios_base::sync_with_stdio(false);
    cin.tie(NULL);
    return 0;
}

Code Example 6

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