#include <iostream>

int main(int argc, char *argv[])
{
    int var1 = 5;
    int *pointer = &var1;
    int var2 = *pointer;

    std::cout << "var1 = " << var1 << "\n";
    std::cout << "pointer = " << pointer << "\n";
    std::cout << "*pointer = " << *pointer << "\n";
    std::cout << "var2 = " << var2 << "\n";

    std::cout << "\n";
}
