Questions tagged [turbo-c]

Turbo C was an Integrated Development Environment and compiler for the C programming language from Borland, released in 1987. It had been re-release as freeware version 2.01 by 2006.

First introduced in 1987, it was noted for its integrated development environment, small size, fast compile speed, comprehensive manuals and low price.

Today, Turbo C is considered obsolete. It is a 16-bit compiler for DOS environments, and as such cannot access more than 640 KB of memory (and even that only with difficulty), and cannot interoperate with 32- and 64-bit code in modern operating systems. Additionally, due to its age, its standard library differs in some significant fashions from modern C libraries. Plainly put, it is not an appropriate tool for many development tasks today.

Despite this, it is sometimes used in introductory C programming courses, particularly in India. Students using Turbo C should keep its limitations in mind.

What is wrong with using turbo C?

I always find that some people (a majority from India) are using turbo C. I cannot find any reason to use such outdated compiler... But I don't know what reasons to give when trying to tell them to use modern compiler(gcc,msvc,...).
