c characters set

C Characters set

A character denotes any alphabet, digits or Special symbol used to represent information.Here We see the valid alphabets, numbers and special symbols allowed in c.

Alphabets :   A,B..........,Y,Z       a,b........., y,z

Digits :         0,1,2,3,4,5,6,7,8,9

Special Symbols :  "  ~ ! @ ' # % & * ( ) _ + - + | \ { }  [ ] : ; ` < > , . ? / ^

different types of c constants

Types Of C Constants 

C Constants can be divided into two major Categories.

• Primary Constants


• Secondary Constants

Primary Constants : Integer Constant , Real Constant , Character Constant.

Secondary Constants: Array, Pointer,Structure,Union,Enum,etc..


Rules for constructing integer constants 

1. An integer constant must have at least one digit.
2. it must not have a decimal point.
3. it can be either positive or negative.
4. if no sign precedes an integer constant is assumed to be positive.
5. no commas or or blanks are allowed with in an integer constant.
6. the allowable range for integer constants is -32768 to 32767. 

Rules For Constructing Real Constants

Real Constants are often called Floating point constants.The real Constants Could be Written in two forms

1. Fractional form 
2. Exponential form

Rules :

Constants Expressed in fractional form

1. A real Constant Must have at least one digit.
2. it must have a decimal point.
3. it could be either positive or negative.
4. default sign is positive.
5. no commas or blanks are allowed within a real constant.

Constants Expressed in Exponential form

1. The mantissa part and the exponential part should be Separated by a letter 'e'.
2. The mantissa part may have a positive or negative sign.
3. Default sign of mantissa part is positive.
4. The exponent must have at least one digit, which must be a positive or negative integer.default sign is positive.
5. Range of real constants expressed in exponential form is -3.4e38 to 3.4e38.

Rules For Constructing Character Constants 

1. A Character constant is a single alphabet, a single digit or a single special symbol enclosed within single inverted commas.Both the inverted commas should point to the left.
2. For Example, 'A' is a valid character constant whereas 'A' is not.
3. The Maximum length of a character constant can be 1 character.

what is c

What is C

History Of C

C is a programming language developed at " AT & T's " Bell Laboratories of USA in 1972. C programming language is designed by man named Dennis Ritchie. In the late seventies C began to replace the more familiar languages of  that time like Algol, PL/I. No One share information about c programming language.

Why c language Mostly Used Programmers

C is most popular language . Because  reliable , simple and Easy to Use. In industry Where newer languages, tools and technology emerge and Vanish day in & day out. That has survived for more than 3 decades has to be really good.

An Option that is often heard today is : "c has been already superceded by Languages like C++,C#,Java. Why bother to Learn c Today". 

There are several reasons Bellow 

• I believe that nobody can learn C++ or Java Directly.Because  While learning These languages you have thing like classes,objects,inheritance, polymorphism,templates, more then. Hence one should first learn all the language elements very Thoroughly Using C language Before migrating to C++,C# or Java.


• C++,C# or Java make use of a principle called Object Oriented Programming ( oop ) To Organize the program.This Organizing principle has lot of Advantages to offer. But, Even while using this organizing principle you will still need a good hold over the language elements of c and basic programming Languages Skills.  


• At Times one is required to very closely interact with the hardware devices. Since C provides Several language elements that make this interaction feasible Without Compromising the performance. it's the preferred choice of the programmer.
