#include <iostream>

using namespace std;

int* func(){
    int i = 3;
    cout<<"In func:"<<endl;
    cout<<"Value = "<<i<<endl;
    cout<<"Address = "<<&i<<endl;
    return &i;
}

int main(){
   int* x = func();
   cout<<"\nIn main:"<<endl;
   cout<<"Value = "<<(*x)<<endl;
    cout<<"Address = "<<x<<endl;
    return 0;
}
