but: but it is easier to maintain because the variable or const is used everywhere, so when I wanted to switch to another delimiter, I only need to change the const or variable. also it could lead to mistyping problems: let's say zero would be the delimiter, when I hit "0" in four cases and in the fifth cases I hit "O" which could, depending on the charset, look very similar. with using a variable or const makes sure, that I always use the same value in all cases. so I prefer using const or variable instead of hardcoding "0" or "#" or whatever is used multiple times. for me it's a best practice. what do you think?
