In 1966, Christopher Strachey assembled a collection of working papers on a language called CPL (Combined Programming Language). It was never actual implemented, but was used basically to study the theory of programming languages.In 1969, Martin Richards took many of the concepts from CPL and produced a more efficient language called Basic CPL or BCPL to aid in writing compilers.Then in 1970, while working on the operating system UNIX for AT&T labs, Ken Thompson decided to write a high-level language so the operating system didn't have to be rewritten in assembly for a new computer that had been purchased. This language was heavily influenced by BCPL and by Thompson's taste for spartan syntax, and was called "B". It was used

In the years that followed, thousands of people wrote code in C, which has proven to be versatile, terse, and relatively low-level; is adequate for most systems programming tasks (like writing an operating system or cutting-edge computer game), and runs everywhere and on everything. Afterward, Stroustrop further refined C++, tweaking the syntax slightly to make it more compatible with C and by adding a slew of features, which facilitate the development of object-oriented programs. Code Examples:CC++:#include *iostream. The only other languages which experience popularity comparable to C++ are C, which is still used by anyone who started programming before C++ was developed, Visual Basic, used to generate easy user-interfaces for custom database applications, Java, which is used for platform-independent application, Perl, which is a sort-of quick-and-dirty glue language used by system administrators, and the legacy FORTRAN and COBOL programs written thirty or more years ago which are still being maintained by pockets of programmers today. htmFor further information:http://www. h*int main(){ std::cout ** "Hello, world!n";}Turing: Put "Hello, world!" ------------------------------------------------------------------------**Bibliography**WORK CITED LIST:C++ information: http://grahammitchell. Pascal enjoyed brief popularity in the academic community because it is easy to learn, but is not well suited for large-scale programming tasks. Today, the majority of new programs are written in C++, especially by large companies. htmlC Language information:http://www. This widespread availability combined with a rich set of operator sand efficient access to the computer hardware made C extremely popular. This process began in December of 1989, when the language specification for C++ was jointly submitted to ANSI/ISO (American National Standards Institute/International Standards Organization).
