Borland's C compiler
for IBM PCs.
Turbo C, version 1.0, was introduced by Borland in 1987. It offered the first integrated edit-compile-run development environment for C
on IBM PCs. It ran in 384KB of memory. It allowed inline assembly, supported all memory models, and offered optimisations for speed, size, constant folding
, and jump elimination.
Version 1.5 shipped on five 360 KB diskettes of uncompressed files, and came with sample C programs, including a stripped down spreadsheet called mcalc.
Turbo C 2.0 has a debugger, a fast assembler, and an extensive graphics library.
Turbo C has been largely supplanted by Turbo C++
, introduced circa September, 1990 for both MS-DOS
and Microsoft Windows
