Conditionals 1. Conditions are like questions. They allow a program to decide to take one action if the answer to a question is true or to do another action if the answer to the question is false. The questions asked within a program are always logical or relational statements. For example, if the variable 'i' is equal to zero then draw a line.

  
   
  size(200, 200);
  background(0);
  
  for(int i=10; i<width; i+=10) {
    // If 'i' divides by 20 with no remainder draw the first line
    // else draw the second line
    if(i%20 == 0) {
      stroke(153);
      line(i, 40, i, height/2);
    } else {
      stroke(102);
      line(i, 20, i, 180); 
    }
  }
