size of integer arrays

How do I in C++ find the size of an integer array? For example, if
int a[] = {1,2,3,4,5};

How would I find the length of that array? Is there anything in C++ that I could use on this array that behaves like strlen for strings? Thanks

Code:

---

#include <iostream>
using std::cout;

int main()
{
        int found=0;
                int array[] = {'1', '2', '3', '4', '5'};

        for(i=0;found==0;i++)
        {
                if(array[i]=='')
                {
                        cout << "The array is " << i << " characters big";
                        found=1;
                }
                else
                {
                        cout << "Still searching...\n";
                }
        }

        return 0;
}

i donno if this works, but something like this

>How would I find the length of that array?

you don't

>Is there anything in C++ that I could use on this array that behaves like strlen for strings?

no

this is technically impossible since no value is reserved for the end of the array.

define a value to size the array or keep track of it by some other means

#define ARRAY_LENGTH 5

and use ARRAY_LENGTH where ever you need the array size
