The for loop has a different structure. It allows us to initialize the variable, set a condition and determine the increment or decrement of that variable all at once. Just by observing the robot, we won't be able to tell whether we are running the while or the for loop. This program will also repeat the forward turn right commands four times. In the real robot C program, do take note that we declare and initialize the count variable right inside the for loops brackets. You may ask why we have two ways of doing the same thing, or which loops should be used in what situations?

In many instances, the answer is that it's your choice, but there is a slight difference. The for loop is better when you want a loop to repeat for a known number of times. Because the command interface allows you to define variables and their increment decrement when you write the for loop The while loop is better when you want the loop to continue until some sensor reading is reached. But you don't know how many times that will take. It is better because the loop continuously check a given sensor reading without having to go through the increment decrements stage
