In order to adequately address the issues with infinite loops, we would first need to understand how loops work. Loops work by repeating a set of predetermined sets of instructions within a loop’s definition body, similar to that of a function’s definition body. Those predetermined instructions will be repeated over and over again until it exceeds the value defined in the loop parameter. Otherwise, it would have to be based on a specific controlling variable. Therefore, infinite loops usually happen in two ways. The first way is when the programmer fails to designate an ending condition within the parameter. The second way is when the programmer fails to implement a controlling variable. The best way to troubleshoot an infinite loop is to gain a comprehensive knowledge of the different types of loops. For example, in C++, a FOR loop’s controlling variable, or in this case, a sentinel value, should be implemented inside of the loop’s parameter parenthesis. In comparison, a while loop requires a designated counter variable inside the loop definition. It is usually the last line of code in the loop definition.
