In 1973, Denis Ritchie, had developed the bases of C. This 'New B', finally called C, introduced in addition, some other new concepts to the language like data types (char). Reason why from 1971, Denis Ritchie, from the Bell Labs team, began the development of a B compiler which, among other things, was able to generate executable code directly.

It had great limitations like it did not compile to executable code but threaded-code, which generates slower code in execution, and therefore was inadequate for the development of an operating system. The final result was an even greater simplification of CPL, although dependent on the system. It was a port of BCPL for a specific machine and system (DEC PDP-7 and UNIX), and was adapted to his particular taste and necessities. In 1970, Ken Thompson, immersed in the development of UNIX at Bell Labs, created the B language. Although it continued being an abstract and somewhat large language. In 1967, Martin Richards developed the BCPL (Basic Combined Programming Language), that signified a simplification of CPL but kept the most important features the language offered. Nevertheless this same specificity made it a big language and, therefore, difficult to learn and implement.

In 1963 the CPL (Combined Programming language) appeared with the idea of being more specific for concrete programming tasks of that time than ALGOL or FORTRAN. Nevertheless ALGOL was an unspecific language and its abstraction made it little practical to solve most commercial tasks. ALGOL 68 also influenced directly in the development of data types in C. Among them, ALGOL 60, was developed as an alternative to FORTRAN but taking from it some concepts of structured programming which would later inspire most procedural languages, such as CPL and its succesors (like C++). Sejarah C & C++ During the 60s, while computers were still in an early stage of development, many new programming languages appeared.
