While Loops vs For Loops - [Which One Should I Use??]

The key to solving this problem, in the most efficient way, is to understand the difference between "for loops" and "while loops" and when to use them. #karel #coding #loops To solve the random hurdles problem in CodeHS you need to know when to use a "for loop" and when to use a "while loop." A "for loop" always loops for set number of times. A "while loop" loops as long as a condition is true. Using a while loop in this problem might seem like a good idea, but it is not. A for loop is better and easier, because we know that EVERY world in this problem is the same size. Since there are 14 columns in the worlds, we need to repeat our steps 13 times to move from the left to the right. The Karel programs can be found at CodeHS.com.
