Introduction to Programming and C Language
In this course, we will be discussing programming in C language.
we will cover some basic concepts such as the need for programming, programming
languages, and how to write programs in C language.
The Need for Programming
Computers are general-purpose machines that can perform any computational task.
However, they can only understand instructions in binary language, which is a
combination of 0s and 1s.
To communicate with a computer, we need to write a sequence of instructions or a
program.
Programs are essential for computers to perform specific tasks.
Programming Languages
Since computers can only understand instructions in binary language,
we need programming languages that can translate human-readable code to computer-
readable code.
Programming languages have their own set of rules, syntaxes, and characters, which
we need to learn before writing programs. High-level languages such as C, C++, and
Java are more understandable to humans than low-level languages such as machine
language and assembly language.
C Language
C language was developed by Dennis Ritchie in 1972 at Bell Laboratories.
It is a high-level programming language that is widely used in system programming,
embedded systems, and operating systems.
C language allows for portability, which means that programs written in C can run
on different machines without modification.
The Development of C Language
C language is considered the successor of B language and was developed by Ken
Thompson.
Its main purpose was to write the kernel of the Unix operating system since the
limitations of B language required a more powerful language.
C is a system programming language used in developing various software and
operating systems such as Oracle, Android, web browsers, and device drivers. It
became the most popular programming language in the 1980s and was standardized by
ANSI in 1989, hence the name ANSI C.
How C Language Works
Unlike machine-level language, C language needs to be converted into object code
using a compiler.
The program is written with a .c extension and is converted into an object file
which contains machine-level code.
The CPU runs the program after the linker and loader have converted it into an
executable file.
