Study Notes
C Programming Language
- C was created by Dennis Ritchie.
- C was originally developed at Bell Labs in the 1970s.
- C has found lasting use in operating systems, embedded systems, and microcontrollers.
Original Purpose and Standardization
- C was originally developed at Bell Labs for developing the Unix operating system.
- C was standardized by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in 1989.
Language Characteristics
- C is a general-purpose, procedural programming language.
- Function parameters in C are passed by value.
- Curly braces (
{ }) are used to group statements into blocks in C. ifandswitchare control flow primitives in C.- C uses static, weak typing.
- The
typedefkeyword allows creating aliases for existing data types in C.
Data Types
- Arrays and structs are aggregate data types that allow related data elements to be accessed and assigned as a unit in C.
- The
unionstructure allows storing different types of data in the same memory location in C. - Pointer arithmetic is used as secondary notation for array indexing in C.
- Whole arrays are assigned in C by using the
=operator to copy the contents of one array to another.
