2D Arrays

2D Arrays

You'll be creating and working with 2D arrays.

We'll dedicate this exercise to...
Alice, a character from the comic strip Dilbert:
Alice

You'll be filling in the code (below) to create the following type of image:

Here's the code with two sections to complete..


		
// Create a board with pink and brown tiles...

size(800,400);

int Nx;    // number of Blocks horizontally (odd number in [11 ... 61]
int Ny;    // number of Blocks vertically = Nx/2

// Choose the number of blocks  Nx: odd number in the range [11 ... 61]
Nx = 21 + 2 * int(random(26));
Ny = Nx/2;

float BlockWidth = width / Nx;  

class Block {
  float xpos;  // top-left
  float ypos;  // top-left
  float bwidth;
  boolean isPink;
  
  Block(float x, float y, float blockwidth) {
    xpos = x;
    ypos = y;
    bwidth = blockwidth;
    isPink = true;  // by default
  }
  
  void display() {
    // ========================== Your illuminating code here...=============
  }
}


Block[][] blocks = new Block[Ny][Nx];
/* Note: by convention the first index is which row, and the second
    index is which column. So...
    blocks[3][1] is the Block in the 4th row from the top, second column
*/


int irow, icol;

// Create the blocks
for (irow = 0; irow < Ny; ++irow)
  for (icol = 0; icol < Nx; ++icol)
    blocks[irow][icol] = new Block(icol*BlockWidth,irow*BlockWidth, BlockWidth);

// ========================== Awaiting thine spotless code ... ==================
// Now go through appropriate members of the blocks to color them brownish

// And now, go though all the blocks and politely ask each to display itself.
