from the July 1985 issue of Unix World magazine by David Spencer Current third-generation languages such as C and FORTRAN will have to move aside at some point for a new family of fourth-generation languages. At 30 years old, FORTRAN is graying at the temples; third-generation programming languages are in their heyday. So you are probably wondering how we will speak to computers during the next decade. If current projections hold true, computers will seem (and talk) more like us fairly soon.

by Bill Tuthill from the January 1985 issue of Unix Review magazine C is descended from B, which was descended from BCPL. BCPL (Basic Combined Programming Language) was developed in 1967 by Martin Richards. B was an interpretive language written in 1970 by Ken Thompson (1) after he abandoned a Fortran implementation for the PDP-7. BCPL and B were typeless languages, which may account for the type permissiveness of C. They restricted their scope to machine words and were rather low level.
