C Language Introduction

C languages developed by Dennis Ritchie in 1972. It was primarily developed as a system programming language for writing an operating system. Key features of the C language include low-level memory access, a simple set of keywords and a clean style; These features make the C language suitable for system programmings, such as the development of an operating system or a compiler. Many later languages borrowed the syntax/resources directly or indirectly from the C language. Like the syntax of Java, PHP, JavaScript, and many other languages, they are mainly based on the C language. C is almost a superset C language ( There are few programs that can be compiled in C, but not in C ).

Why learn C Programming?

The C programming language is a must for students and professionals who want to become great software engineer, especially when working in the field of software development.

• Easy to learn
• Structured language
• It produces efficient programs
• It can handle low-level activities
• It can be compiled on variety of computer platforms

Applications of C Programming

The C programming language can be used to design different types of applications, such as

• System Software Design, 
• Operating system 
• Compiler.
• Design of application software such as Databases and Spreadsheets.

Facts about C

• C was invented to write an operating system called UNIX.
• It is the successor of the B language introduced in the early 70s.
• The language was formalized in 1988 by the American National Standard Institute (ANSI).
• The UNIX operating system was written entirely in C.
• Today C is the most used and popular system programming language.
• The most advanced software has been implemented using C.
• Today’s most popular Linux operating system and MySQL RDBMS were written in C.

C Functions :

 Introduction:  A function is a group of instructions that together perform an activity. Each C program has at least one function, which is main (), and all commonplace programs can define additional functions. You decide how to divide the code between different functions, but logically the division is such that each function performs a specific task. A function declaration tells the compiler a function name, a return type, and parameters. A role definition provides the actual body of the role. The standard C library provides a set of integrated functions that can be called from the program.

For example, strcat () to concatenate two strings, memcpy () to copy a memory location to another location, and many other functions.

A function can also be designated as a method, subroutine or procedure, etc.

• Return_type is data type of the value returned by the function.
• Some functions perform desired operations without returning a value.
• In this case, return_type is the void keyword.
• Function name: this is the real name of the function.
• The name of the function and the list of parameters together make up the signature of the function.
• When a function is called, it passes a value to the parameter.
• This value is called an actual parameter or argument.
• The list of parameters refers to the type, order, and a number of parameters of a function.
• The parameters are optional; that is, a function cannot contain any parameters.
