Successors of C language
C and even B have several direct descendants, through they do not rival pascal. One side branch developed early. When Steven Johnson visited the University of Waterloo on sabbatical in 1972, he brought B with him. It became popular on the Honeywell machines there, and later spawned Eh and Zed (the Canadian answers to 'what follows B?'). When Johnson returned to Bell Labs in 1973, he was disconcerted to find the language whose seeds he brought to Canada had evolved back home; even his own yacc program had been rewritten in C, by Alan Snyder.
More recent descendants of C proper include Concurrent C, Objective C, C* and especially C++. The language is also widely used as an intermediate representation (essentially, as a portable assembly language) for a wide variety of compilers, both for direct descendants like C++, and independent languages like Modula 3 and Eiffel.
