Introduction to Programming and C Language
In this course, we will be discussing programming in C language. In this first
video, 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. The complete
process of execution is discussed in a separate video. C language can also be
interpreted, but the difference will be discussed in another video.
