C/C++ is a procedural programming language developed in the 1970s. C++ builds on C and adds object-oriented programming capabilities. Some key differences between C and C++ include C++ supporting classes, function overloading, and operator overloading. C++ is commonly used to create operating systems, compilers, databases, games, and other application software. The document then discusses C++ history, creators, uses, data types, variables, operators, control flow statements like if/else and loops, arrays, and multi-dimensional arrays. It provides examples of C++ code and basics of the C++ programming language.
