May 22, 2017 · The year after, the American standard was accepted internationally and published by ISO (ISO 9899:1990). This release is called C90. Technically, it is the same standard as C89/ANSI-C. Formally, it replaced C89/ANSI-C, making them obsolete. From 1990-1999, C90 was "the C language".

A lot has been written about the history of C and I am not going to repeat it. All I want to say is that C was developed by Dennis Ritchie between 1969 and 1973 at Bell Labs. It was widely accepted by almost all the professional programmers immediately, and they started making their own additions to it. After a few years, there were a lot of C vari...
Even though K&R C was accepted by many programmers as the de facto standard of C, it was not the de jurestandard, and nobody could have been coaxed into accepting it as the official standard of C. So, it was absolutely essential for some standards organisation to accept the challenge of coming up with an official standard for C. The American Nation...
C99 is the informal name given to the ISO/IEC 9899:1999 standards specification for C that was adopted in 1999. The C99 standard added five more keywords to ANSI C, and the total number of keywords became 37. The keywords added in C99 are _Bool, _Complex, _Imaginary, inline and restrict. The keyword _Bool is used to declare a new integer type capab...
C11 is the current and latest standard of the C programming language and, as the name suggests, this standard was adopted in 2011. The formal document describing the C11 standard is called ISO/IEC 9899:2011. With C11, seven more keywords were added to the C programming language, thereby making the total number of keywords, 44. The seven keywords ad...
The standard known as Embedded C is slightly different from all the others. C from K&R C to C11 depicts the changes of a programming language over time, based on user requirements. But the Embedded C standard was proposed to customise the C language in such a way that it can cater to the needs of embedded system programmers. While the other standar...
Oct 11, 2024 · The C programming language has several standard versions, with the most commonly used ones being C89/C90, C99, C11, and C18. C89/C90 (ANSI C or ISO C) was the first standardized version of the language, released in 1989 and 1990, respectively.
Jul 22, 2024 · Some of the notable compilers that supported ANSI C/C89 include: GCC (GNU Compiler Collection): One of the first compilers to adopt the ANSI C standard and continues to support it robustly. Microsoft C/C++ Compiler: Microsoft Visual C++ (MSVC) added support for ANSI C in its early versions and continues to support ANSI C alongside C++.
Hence, ANSI C is also commonly referred to as ISO C, or the more generic Standard C. Some differences between C and ANSI C: ANSI C allows the inclusion of a function prototype which gives the type of the function and the type of each parameter before defining the function. In C, function declarations are assumed by default to be of type int ...
ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22/WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

Sep 1, 2013 · In 1983, the American National Standards Institute (ANSI) formed the X3J11 committee that developed the first ANSI C known as C89. It was essentially based on the standard UNIX C compiler of the time.
