two dimensional array , matrix
« on: June 02, 2012, 10:56:27 AM »
can anybody tell me the idea to solve this program, not the whole answer. I am a beginner.


Use a matrix represents an island surrounded by water. Two bridges lead out of
the island. A mouse is placed on the black square. Write a program to make the
mouse take a walk across the island. The mouse is allowed to travel one square
at a time, either horizontally or vertically. A random number from 1 through 4
should be used to decide which direction the mouse is to take. The mouse drowns
when he hits the water; he escapes when he enters a bridge. You may generate a
random number up to 100 times. If the mouse does not find his way by the
hundredth try, he will die of starvation. Restart the mouse in a reinitialized
array and go back and repeat the whole process. Count the number of times he
escapes, drowns, and starves.
Input File
1.  First input line - the size of the array, including border of water and
    bridges (not larger than 20 X 20)
2.  Next N input lines-the rows of the two-dimensional array, where the
    positions containing negative numbers represent the water, the positions in
    the edge containing a 0 represent the bridges, the position containing a 1
    represents the starting position of the mouse, and all other positions
    contain 0s.
Output
1.  A line stating whether the mouse escaped, drowned, or starved
2.  A line showing the mouse's starting position and the position of the two
    bridges
3.  A map showing the frequency of the mouse's visits to each position

Try first to create a sample input file and write the code to read it in.
Try to find an algorithmus with a pencil and squared paper. Write your algorithmus down in english phrases. Learn how to use pseudo random numbers in C.
