#include <iostream>


int main()
{
    int a{ 10 };
    int b{ 12 };
    int c{ 15 };

    std::cerr << "a="<<a<<std::endl;
    std::cerr <<"Let's execute a++" << std::endl;
    a++;
    std::cerr << "a=" << a << std::endl;
    std::cerr << std::endl;
    std::cerr << "b=" << b << std::endl;
    std::cerr << "Let's execute ++b" << std::endl;
    ++b;
    std::cerr << "b=" << b << std::endl;
    std::cerr << std::endl;
    std::cerr << "a=" << a << " b=" << b << std::endl;
    std::cerr << "Let's execute c = a + ++b" << std::endl;
    c = a + ++b;
    std::cerr << "a=" << a << " b=" << b << " c=" <<c<<std::endl;
    std::cerr << std::endl;
    std::cerr << "a=" << a << " b=" << b << std::endl;
    std::cerr << "Let's execute c = a +b++" << std::endl;
    c = a + b++;
    std::cerr << "a=" << a << " b=" << b << " c=" << c << std::endl;
    return 0;
