Lab 4 : Syntax error

1. the local variable "space" may not have been initialized.

cause of problem : forgot to set a value of space

solution : set a value to space   --->   int space=0;

2. Error on "::IdentifierOrNew"

          expecting SEMI, found 'draw_balloon'

cause of problem : forgot a ; after y=(y+10)%height

solution : put a ; after that

3. Found one too many { characters without a } to match it

cause of problem : forgot a } after return sum;

solution : put a } after that
