```The "int" prefix is a variant of Hungarian Notation adopted by MS . Originally developed by
the Hungarian Chief Architect at Microsoft in the '80s. when he was at PARC in the '70s.
It's fallen out of favour thee days, but I still use it all the time and find it very intuitive when
maintaining old code :)

Lots of the supposed origin for the use  of "i" and "j" for loopcounters.
Among others:
i-m as variables that default to integer in Fortran,
i- for iterator
i has a long history in mathematical notation of indices of summations etc.
i,j.k in in the name Dijkstra  :)
