How to find the minimum and maximum element of an Array using STL in C++?

Given an array arr[], find the minimum and maximum element of this array using STL in C++.
Example:

Input: arr[] = {1, 45, 54, 71, 76, 12}
Output: min = 1, max = 76

Input: arr[] = {10, 7, 5, 4, 6, 12}
Output: min = 4, max = 12

Approach:

• Min or Minimum element can be found with the help of *min_element() function provided in STL.
• Max or Maximum element can be found with the help of *max_element() function provided in STL.

Syntax:

*min_element (first, last);

*max_element (first, last);

To use *min_element() and *max_element() you must include “algorithm” as a header file.

The range used is [first,last), which contains all the elements between first and last, including the element pointed by first but not the element pointed by last.

Below is the implementation of the above approach:

CPP

 // C++ program to find the min and max element// of Array using sort() in STL #include using namespace std; int main(){    // Get the array    int arr[] = { 1, 45, 54, 71, 76, 12 };     // Compute the sizes    int n = sizeof(arr) / sizeof(arr);     // Print the array    cout << "Array: ";    for (int i = 0; i < n; i++)        cout << arr[i] << " ";     // Find the minimum element    cout << "\nMin Element = "         << *min_element(arr, arr + n);     // Find the maximum element    cout << "\nMax Element = "         << *max_element(arr, arr + n);    // Storing the pointer in an address    int &min = *min_element(arr,arr+n );    int &max = *max_element(arr,arr+n );    cout<<"\nFinding the Element using address variable";    cout<<"\nMin Element = "<
Output
Array: 1 45 54 71 76 12
Min Element = 1
Max Element = 76
Finding the Element using address variable
Min Element = 1
Max Element = 76
