#include<iostream>
using namespace std;
int main(){
	int a=1, b=2;
	cout << "a = " << a << ", b = " << b << endl;
	cout << "a-- + 1     = " << a-- + 1 << endl;
	cout << "          a = " << a << endl;
	a = 1;
	cout << "--a + 1     = " << --a + 1 << endl;
	cout << "          a = " << a << endl;
	a = 1;
	b = 2;
	cout << "a + --b + 3 = " <<  a+ --b * 3 << endl;
	cout << "          b = " << b << endl;
	b = 2;
	cout << "a + --b * 3 = " << a +  --b * 3 << endl;
	cout << "          b = " << b << endl;
	return 0;
