Question
This program implements a primitive game in which the player tries to find a pot of gold.
Behavior: the game is played on an implicit grid of 2D coordinates. The grid boundaries
are:
Left: 0
Right: 10
Bottom: 0
Top: 10
Initially, the player is placed at coordinate (5,5).
The program places the pot of gold at a random location on the grid that is distinct from
(5,5). (The player has to do at least some work to get rich).
Behavior:
The program prompts the user to enter a direction to move as a single char
n (north)
s (south)
e (east)
w (west)
If any other letter is entered, an error message is printed and the user is
reprompted.
If a valid direction is entered, the following happens:
If the move would result in the player leaving the board, the program
prints
