I have heard that the reason the
i variable is used so much is because there was an old computer where each variable could only be a single letter and that reserved the variables
h as internal variables, leaving
i as the first one available to the programmer. This seems believable, as there would be exactly 8 reserved variables which is a nice binary number. I haven't been able to confirm or deny this story.
Is this true? If so, what system was the origin of this behaviour? If it's not true, why was
i used so much in the past?
