Each player throws a part of dice to determine how many squares his/her game piece will advance. If the piece lands on the bottom of a ladder, the piece moves up to the square at the top of the ladder. If the piece lands on the top of a snake, the piece "slides" down to the square at the bottom of the snake. If the piece lands on the last square, the player wins. If the piece cannon advance the number of squares indicated by the dice, the piece in not moved at all.

In order to help you play this game via a cell phone while travelling, you will write a program that simulates your moves on the board shown and, ofcourse, runs on your handheld computer. If you got a handheld computer, why are you playing in snakes&ladder via cellphone?! - Confused Tony You will repeatedly throw the dice and enter the result into the program. After each throw the program will report the number of the square wher your piece lands.

When the program starts it should assume the piece is on square 1. It should repeatedly read input from the user (a number meaning integer between 2 and 12) and report the number of the square where the peice lands. In addition, if the piece moves to the last square, the program should print "You Win!" and terminate. If the user enter 0 instead of a number between 2 and 12, the program should print "You Quit!" and terminate.

For clarity, you are to use the board pciture above and you should note that the board has 3 snakes (from 54 to 19, from 90 to 48, from 99 to 77) and 3 ladders (from 9 to 34, from 40 to 64 and from 67 to 86).

The board itself is 100 squares long, you win when you reach 100th square

Solution by JSBN

var sum : int
var loca : int := 1

    put "Enter sum of dice:"
    get sum

    if sum = 0 then
        put "You Quit!"
    end if
    if loca + sum > 100 then
        loca := loca + sum
    end if
    if loca = 9 then
        loca := 34
    elsif loca = 40 then
        loca := 64
    elsif loca = 67 then
        loca := 86
    elsif loca = 99 then
        loca := 77
    elsif loca = 90 then
        loca := 48
    elsif loca = 54 then
        loca := 19
    end if

    put "You are now on square ", loca
    exit when loca = 100
end loop
put "You Win!"

This is easier then both J1 and J2... what were they thinking?
