cout<<a;
7
 What is the output of following program?
int x = 10,y;
y = x++;
cout<<y;
int x = 10,y;
y = x++;
cout<<x;
int x = 10;
x++;
cout<<x;
int x = 10,y;
y = ++x;
cout<<y;
int x = 10;
cout<<++x;
int x = 10;
cout<<x++;
8

int x = 10;
cout<<x<<x++;
int x = 10;
cout<<++x<<x++<<x;
int x = 10;
cout<<x++<<x<<++x;
int x = 10,y;
y = x + x++;
cout<<y;
int x = 10,y;
y = ++x + x++ + x;
cout<<y;
int x = 10,y;
y = x++ + x + ++x;
cout<<y;
