Introduction to C Language

 C Language

C is a procedural programming language .

C was originally developed by Dennis Ritchie at AT & T Bell Laboratories & It was designed to run on a PDP-11 with a Unix Operating system.

It is a structured programming language .

C is often termed as  a middle level programming language because it combines the power of  a high level language  with the flexibility of a low level language. 

C can be used for a whole range of applications with equal ease and efficiency.

These are several features which make C a very suitable language for writing system programs :-

1. C is a machine independent and highly portable language.

2. It is easy to learn as it has only as few as 32 keywords.

3. It has a comprehensive set of set of operators to take business as well as scientific applications with ease.

4. C language allows manipulation of  BITS, BYTES, and ADDRESSES at hardware level. 

5. It has a large library of functions.

The C program code for this function looks like :-

Int FindMax ( int a, int b )

{

statement 1;

statement 2;

return (p);    // p is the integer value returned by .

//this function.

}

Data Types

Data type is used to define the type of value to be used in a programme.

Based on the type of value specified amount of required bytes will be allocated to the variables used in the program.

Three main types :-

1. Primary Data Type.

2. Derived Data Type.

3. User Defined Data Type.
