trying to solve a problem

freqs.cpp

// Make a subprogram void freqNumbers(int freqs[], int min, int max)to read
// numbers between min and max, until a number out of this range is entered.
// Then, the subprogram must return the frequencies of every number, and then
// in the main() print on the screen every number with its frequency. Try it
// with 0 and 9 for min and max. For example:
// Input: 1 8 7 3 4 8 5 9 5 0 0 4 8 4 5 3 2 8 -1
// Output: 0:2; 1:1; 2:1; 3:2; 4:3; 5:3; 6:0; 7:1; 8:4; 9:1


#include <iostream>
using namespace std;
void freqNumbers (int freqs[], int min, int max)
{
    // Okey , my problem is here. I managed to do an algorythm that creates an
    // array with a not given dimension, so it depends on the number of
    // numbers that the user enters.

    //     The problem is that i dont know the way to make the subprogram
    //     freqNumbers know the size of freqs[] array.

int main()
{
    int min = 0;
    int max = 9;
    int x;
    int i = 0;
    int freqs[i];
    cout << "Introduce numbers between 0 and 9, or a number"
            " out of range, so the program ends:" << endl;
    cin >> x;
    while (x > min && x < max) {
        freqs[i] = x;
        ++i;
        cin >> x;
    }
    for (int j = 0; j < i; j++) {
        cout << freqs[j];
    }
    freqNumbers(freqs, min, max);
