Lets say you use a variable named abcd in your function. And a variable named abcb in a for loop inside the same function. But because reasons you mistakenly use abcd inside that loop and modify the wrong variable, so that your code sometimes doesnt work properly.

A similar thing is to use const when the variable is not modified.
