How to print the N largest numbers in array with C++

Answer 1

#include <iostream>
#include <algorithm>

void printNLargest(int arr[], int size, int N) {
    sort(arr, arr + size, std::greater<int>());
 
    for (int i = 0; i < N; i++)
        std::cout << arr[i] << " ";
}
 
int main()
{
    int arr[] = { 50, 99, 20, 100, 76, 33, 87, 40, 80  };
    int size = sizeof(arr) / sizeof(arr[0]);
    int N = 4;
    
    printNLargest(arr, size, N);
}
