#include<conio.h>
void main()
{
int a, b;
a = 20;
b = -10;
clrscr();
a = ++a;
cout<< "The new value of a is: " << a << "\n";
b = ++b;
cout<< "The new value of b is: " << b << "\n";
a = a * --b;
cout<< "The new value of a is: " << a << "\n";
a = a + 154;
cout<< "The new value of a is: " << a << "\n";
b = a++ * b;
cout<< "The new value of b is: " << b << "\n";
