C is a universal programming language developed by Dennis Rich in 1972 and is known for its efficiency, portability and widespread use. Reasons for learning C include its fundamentality (the foundation of many operating systems and applications), an in-depth understanding of how the internal workings of computer systems are, and its fast and efficient features (for real-time systems and embedded device programming).

What is C language?

C is a common programming language developed by Dennis Rich in 1972. It is known for its efficiency, portability and wide range of applications.

Why learn C?

• The C language is the basis of many operating systems and applications, such as Linux, UNIX, and Windows.
• Understanding C language can help to gain an in-depth understanding of how computer systems work internally.
• The C language is known for its speed and efficiency, making it ideal for programming real-time systems and embedded devices.

The basics of C language

• Data Type: C language provides various data types, such as integers, characters, and floating point numbers.
• Variables: Variables store data, and you can declare them using data types.
• Operator: Operators are used to perform mathematical and logical operations.
• Statement: Statement is used to control program flow.
• Function: A function is a set of encapsulated blocks of code that are used to perform specific tasks.

C language program structure

A basic C program usually contains the following parts:

• The header file contains declarations of functions and data types.
• The main function is the entry point of the program.
• Other functions perform specific tasks.
• Global variables are visible throughout the program.
• Local variables are only visible within the scope of the function.

Steps to learn C language

• The basics of familiarity with C language.
• Practice writing simple programs.
• Learn advanced concepts such as pointers and data structures.
• Write more complex and useful programs.
