Write a program that:

Declare two variables; initialize the second variable to

be $1000$

Gets a value of the first variable from the user

If the first variable is $0,$ the program increments the

first variable

If the first variable is $1,$ the program decrements the

first variable and increments the second variable

If they first variable is $-100,$ the program increments

the first variable and decrements the second variable

In all other cases, the program sets both variables to $0$
