/** * 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); } }
