Every call after this, incrementCounter serves as a reference for the inner function (referred to by increment).As such, the line incrementCounter(1) actually invokes the increment function with parameter 1. If incrementation exceeds the set, i.e. [code] int max_num = 100; //max_num is the number you want to count to int count = 0; while (count < max_num) count+=2; printf("%d", count);[/code] The task is to increment/decrement alphabetic letters using ASCII value with the help of JavaScript.

Approach: Use charCodeAt() method to return the Unicode of the character at the specified index in a string; Increment/Decrement the ASCII value depending on the requirement. This is not always the case, JavaScript doesn't care. Use fromCharCode() method to convert Unicode values into characters. Thx i += 2; that's the same as i = i + 2; I don't think there's a way to use the ++ operator to increment by 2... unless this works: (i++)++; 0 0. hektner. 4 Answers.
