How to find largest number in array

[nicknack125]

Does anybody have any ideas on how to find the largest number in an array, but keep the location it's stored in? For instance, I want to find the largest number in array "frequency[8]", and still know whether it's stored in "frequency[0]", "frequency[1]" and so on.

The function max_element() does that in C++.

#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
    int frequency[8] = {1,2,3,10,5,6,7,-8};
    int* p = max_element(frequency, frequency+8);
    cout << "The largest number is " << *p
         << " and it is in frequency[" << (p - frequency) << "]\n";
}

Got it - also, since I'm still kind of a beginner, what's with the "*" symbol before variable p in line 6/7? Also, how would you suggest reading from that? I also need to then set the value of an integer to where the value of "frequency" is saved. (For example, I need to make integer "p1turn" where the highest number is stored - from the code sample above, that would be in "frequency[3]" so p1turn = 3.

It means 'p' is a pointer to a integer. You must have almost just began C++, as it is very common for average users to use pointers.
