How do I find the maximum value in an array using C++?

You can use a simple loop to iterate through the array and keep track of the maximum value. Would you like to see a code example?

Yes, please show me the code example.

Here's a basic example:

#include <iostream>
using namespace std;

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int max = arr[0];
    for(int i = 1; i < 5; i++) {
        if(arr[i] > max) {
            max = arr[i];
        }
    }
    cout << "Maximum value: " << max;
    return 0;
}

What if the array has negative numbers?

The code will still work! It initializes max to the first element, so it will correctly identify the maximum even if all numbers are negative.
