C++ Language Foundations and Standards

Origins: C with Classes to C++

“C with Classes” was the direct predecessor of C++. In 1979, Bjarne Stroustrup began work on this language as an extension of C, aiming to keep C’s efficiency and flexibility while adding higher-level program organization. The initial “C with Classes” approach extended the C compiler (Cpre) with class-related features such as classes and derived classes, along with strong typing, inlining, and default arguments. As Stroustrup progressed, he moved toward a more traditional compiler-based design. In 1982, he began designing a cleaned-up and extended successor to “C with Classes,” briefly called C84 before adopting the name C++. The resulting language incorporated core object-oriented and C-like capabilities, including virtual functions, function and operator overloading, references, const, improved type checking, user-controlled dynamic memory allocation (new/delete), and // single-line comments. This evolution from “C with Classes” to C++ established the foundation for later standardization and feature growth.
