I am tring to get this program together and can't seem to make it work. Ok. . this program is to take in a file with a matrix of zeros and numbers 1-9. The zeros are shaded and the numbers are part of a block. All numbers and the ones directly beside them make a block. the program is to count the squares in each block and tell me how many block and squares ther are.
0 0 0 0 0 0 0 0
0 0 4 0 0 0 1 0
0 0 2 2 0 0 2 0
0 0 3 0 0 3 3 0
0 0 0 0 4 4 0 0
0 5 0 0 5 0 0 0
0 6 0 0 6 6 0 0
0 0 0 0 0 0 0 0
The borders of the matrix must be shaded. The out put of this program with this file should be:
block 1 contains 4 squares
block 2 contains 9 squares
block 3 contains 2 squares
Ok so I keep getting the wrong out put from the program and don't know where I'm going wrong
can anyone help me?
