Hi Friends!
The Video is all about the basics of C language that every programmer should know about it
C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.C has now become a widely used professional language for various reasons:
 Easy to learn
 Structured language
 It produces efficient programs
 It can handle low-level activities
 It can be compiled on a variety of computer platforms
The simplest program is of Hello World.
You have seen the basic structure of a C program, so it will be easy to
understand other basic building blocks of the C programming language. A C program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol.
For Example:
Semicolon, Comments.
The Other thing is datatypes
Data types in C refer to an extensive system used for declaring variables or
functions of different types. The type of a variable determines how much space
it occupies in storage and how the bit pattern stored is interpreted.
like int, string, float, char, double etc.
A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in C has a specific type, which determines the size and layout of the variable's memory.
The name of a variable can be composed of letters, digits, and the underscore character. It must begin with either a letter or an underscore. Upper and lowercase letters are distinct because C is case-sensitive. Constants refer to fixed values that the program may not alter during its execution. These fixed values are also called literals. Example has been shown in video
