running total. The player who adds a value that makes the total points exceed 21, loses the game.
Create a game of Count 21 in which two players compete against each other. On any turn, if the
player enters a value other than 1, 2 or 3, force the player to re-enter the value. The output for
the game should look similar as the following for the first pass write desk checking

Answer 1

 

  I have posted the code in java under Count21.source

 

 you will have to rename the file to Count.java

and then compile it

 

 You can get the algorithm and pseudo code from there..

 

 it's basically a nested while loop...

 the inside one traps the input 1,2,3

the outside traps the sum > 21
