The roots of the C programming language can be traced back to its precursor, ALGOL 60 (algorithmic language), introduced in 1960 as the first programming language employing a block structure. Derived from ALGOL, Martin Richards developed BCPL (Basic Combined Programming Language), a typeless high-level language.
The C language developed by Dennis Ritchie in 1972. In 1970, Ken Thompson built upon BCPL to create a typeless language called B. Subsequently, Dennis Ritchie at AT&T Bell Labs took charge of the C language’s development in 1972, drawing inspiration from the foundations laid by BCPL and B.
Initially used to re-implement the Unix operating system, C gained popularity for its portability and efficiency. The Unix operating system, initiated in 1969, underwent a rewrite in C in 1972.
The release of Windows 1.0 in 1985, while not publicly disclosing its source code, reportedly featured a kernel predominantly written in K programming language.
Linux, a prominent operating system, commenced development in 1991 using C and Lisp. After nearly a year of development, Linux was released under the GNU license, forming part of the GNU operating system.
Oracle, a widely-used relational database management system (RDBMS), began development in 1977. In 1983, its code transitioned from assembly language to the C programming language (3rd edition).
To establish C as a standard, the American National Standards Institute (ANSI) defined a commercial standard for the language in 1989. Subsequently, this standard gained approval from the International Standards Organization (ISO) in 1990, leading to the term “ANSI C.”

Make C programming language history notes to understand its history and origin clearly. C++, Java, and other languages have evolved from C, finding widespread application in various technologies. As such, C serves as a foundational language for many others currently in use.

Who Invented C++ and C?

How Does C Programming Work?

C language serves as a compiled programming language extensively utilized for system programming, embedded systems, and various low-level applications. The creation and execution of a C program involve several sequential steps, encompassing preprocessing, compiling, linking, and execution.

1) Program Creation:

Initiating the use of C begins with program creation. This entails crafting the source code in a text editor or integrated development environment (IDE), constituting a set of raw instructions that delineate the program’s behavior.

2) Preprocessing:

Following program creation, preprocessing becomes imperative. This phase incorporates running the source code through a preprocessor—an application executing specific operations on the code before compilation. Operations may include inserting header files, expanding macros, and performing conditional compilation.

3) Compiling the Program:

Subsequent to preprocessing, the program undergoes compilation. This process involves translating the source code into machine code executable by the computer’s processor. The compiler reads the source code and generates an object file containing the compiled code.

4) Linking the Program with C Library Functions:

Post-compilation, linking ensues, necessitating the program to be linked with functions from the C library. The C library comprises prewritten functions accessible to C programs. Linking amalgamates the object file produced by the compiler with the essential functions from the C library, culminating in an executable program.

5) Executing the Program:

The concluding step entails program execution. The executable file, fashioned in the preceding step, is run by the operating system. The operating system loads the program into memory, initiating its execution. The program proceeds to perform its designated operations until termination or interruption occurs.
