Pointer object calling a constructor gives some other not expected result

#include <iostream>
using namespace std;


class Test 
{
    public:
  int x;
  
  Test() { x = 5;}
};
 
int main()
{
   Test *t;

   cout << t->x;

}

It should print "5" but instead, it prints "1528349827". Test *t should initialize x by 5. and t->x should print 5. But it gives the above number. Can someone please explaint to me what's happening.
