How to convert from tenerary (conditional operator) to if/else statement

tomasmahmoudian

if(board[j][i] > 0) {
  fill(board[j][i] ==1?255:0, board[j][i] ==2?255:0,0); 
  ellipse (i * bs, j * bs, bs, bs); 

--How would I go about changing this to an if else statement instead of the '?'

there are TWO tenerarys:

• board[j][i] ==1?255:0

• board[j][i] ==2?255:0

Both ask essentially :

• Is board[j][i] == 1 then return 255 else return 0

• Is board[j][i] == 2 then return 255 else return 0

Both resulting values are used in a fill statement.

In a 2D grid (chess board) that leads to different colors based on the value of board[j][i]

New version:

if(board[j][i] > 0) {     

    int redValue=0;
    int greenValue=0; 

    if(board[j][i] == 1)
        redValue=255;
        else 
        redValue=0;

    if(board[j][i] == 2)
        greenValue=255;
        else 
        greenValue=0;


    fill(redValue,greenValue,0); 

    ellipse (i * bs, j * bs, 
          bs, bs);

}// if
