How to find the number of elements in an array and pass it to a function in this code?

Question

#include <iostream>

using namespace std;

int aver(int data[])
{
float add=0;
int n;

for(int i = 0; i <=my_num-2; ++i) //I need to pass the number of elements on the array in the main function//
{
cout<<"value of i "<<i<<" ";
cout<<num<<" ";
cout<< data[i] << ' '<<"Array No. "<<i+1<<endl;
int x=sizeof(data);
add=add+data[i];
cout<<endl;
n=i+1;
}
cout<<"The addition is = "<<add<<endl;
float ave=add/n;
cout<<"The Average of the six numbers is = "<<ave<<endl;
}

int main()
{
int num=0;

cout<<"This Program Adds the elements of an Array"<<endl;
cout<<" And calculates their Average"<<endl<<endl;
cout<<"how many elements do you want in the Array? ";
cin>>num;
int data[num];
for(int j=0;j<=(num-1); ++j){
data[num];
cout<<"enter "<<j<<" Element ";
cin>>data[j];
}
int my_num=num
aver(data);

}
