Program : Compute the maximum and minimum values in a 1-D array in C++.

Solution :

#include <iostream>
using namespace std;

int main() {
    const int size = 5; // Change the size to fit your array
    int arr[size], i, max, min;

    
    cout << "Enter " << size << " elements of an array:\n";
    for (int i = 0; i < size; i++) {
        cin >> arr[i];
    }

    max = arr[0];
    min = arr[0];

    for (i = 1; i < size; i++) {
        if (arr[i] > max) {
            max = arr[i];
        }
        if (arr[i] < min) {
            min = arr[i];
        }
    }

    cout << "Maximum value: " << max << endl;
    cout << "Minimum value: " << min << endl;

    return 0;
}

Output :

Enter 5 elements of an array: 
10 
12 
33 
4 
35 
Maximum value: 35
Minimum value: 4

Dry Run :

max is arr[0] i.e. 10.

min is arr[0] i.e. 10.

So, from the above table, final value of max is 35 and min is 4.
