Insert the appropriate value of x and y. Then rewrite the following as pre-increment or post-increment operators:

1.

int x = 0; x: __________________

cout << x; x: __________________

x = x + 1; x: __________________

rewrite: __________________________________________________________

2.

int x = 3, y = 0; x: __________________ y: __________________

x = x + 1; x: __________________

y = x; y: __________________

rewrite: __________________________________________________________

3.

int x = 3, y = 0; x: __________________ y: __________________

y = x; y: __________________

x = x + 1; x: __________________

rewrite: __________________________________________________________

4.

int x = 0; x: __________________

int y = x; y: __________________

x -= 1; x: __________________

rewrite: __________________________________________________________
