Trying to create a random number generator using Arrays and getting Identifier "i" is Undefined. Can anyone see the problem?

Trying to create a random number generator using Arrays, but the " a[i] = rand();" portion of my code creates an error of the type "Identifier i is Undefined". Can anyone find where I am going wrong here? Thanks

#include <iostream>
#include <string>
#include <array>

using namespace std;


int main()
{
    int a[10] = {};  
  
   
    for (int i = 0; i < size(a); i++); {

        a[i] = rand();

    }

    for (int i = 0; i < size(a); i++) {

        cout << "The random number is: " << a[i] << endl;

    }
    
}
