C++ evolved from C, which was developed by Dennis Ritchie at Bell Laboratories. C is available for most computers and is hardware independent. With careful design, it’s possible to write C programs that are portable to most computers.
The widespread use of C with various kinds of computers (sometimes called hardware platforms) unfortunately led to many variations. A standard version of C was needed. The American National Standards Institute (ANSI) cooperated with the International Organization for Standardization (ISO) to standardize C worldwide; the joint standard document was published in 1990 and is referred to as ANSI/ISO 9899: 1990.
