The three simple things you can do are to talk through your code, output values at runtime, and generate progress messages. silly as it sounds, talking through your code really works. Do it out loud as if you're explaining your code to another programmer. So here goes in this program. The line 15 is a while loop and it's going to repeat as long as the value of variable x is less than 10, line 17 outputs to the value of variable X, but it adds one to it so that humans won't be confused and line 18 calls the whatever function and then the loop repeats at line 15 as long as the value of x is, oh, nowhere in here, am I modifying the value of variable x. It never increases, so the loop just keeps repeating. Wow, this example may seem silly, but I've caught dozens of bugs talking my way through…
