From what i understand this statement has the program repeat execution of a calculation until a goal is reached (i.e. a boolean value is proved false after being true for x number of calculations)
This is very useful for a variety of calculations, and has endless practical and semi-practical applications.
To be honest, i deven know if imma be using this in my program, but i sense the need to declare around 400 variables. 
(big man ting)









   
  
 
 
   

 
 
I think u will be using the do while loop! unlike the for and while loop the do while loop allow u to execute the loop at lease once! its very useful!!!!!!!!

Glad to see u learning!!!! i'm PROUD.........
