![Character set
Character set means that the characters and symbols that a C program can
understand and accept. These are grouped from the commands, expressions, words,
co-statements and other tokens for C language.
Character set is the combination of alphabet, digit, special characters and white
space.
EXAMPLE= ,..,/,;,’,[,], and so on.

![TOKENS
the blank space are called tokens. In c program all the C- statements having keywords, identifiers, constant, strings,
operators and special symbols are called c-tokens.
For example , some C-tokens used in a c-programing are:
Reverse words: float, do, if etc
Constant : 300.9, 20.99, -098 etc
Strings: “raman”, “2002-03”etc
Operators: +,=,-,<> etc
Special symbols:{},[],() @, #, $, % etc](https://image.slidesharecdn.com/presentationofc2-170904174211/85/Presentation-of-c2-7-320.jpg)
Presentation of c2
- 1. Presentation of C Subject :- Introduction to C Submitted to:- Miss. Diya Sharma Submitted by :- Lovepreet (023)
- 2. C language C is a general purpose structured powerful modern language. It is a high level language and low level too. This language was designed for developing fast, reliable , efficient, economical and portable system software. Built-in functions More operators then other Simple to learn
- 3. Algorithum a sequence of instructions designed in such a way that if the instructions are executed in some specified sequence, the desired result will be obtained. Ex:- STEP 1 : INPUT a, b, STEP 2 : sum = a+b Step 3 = Write “Sum of two number”, SUM Step 4 = END
- 4. Compiler and Interpreator Compiler converts all the source code into machine code, creating an executable file. As interpreter also converts source code to machine code and it done only a line at a time
- 5. Character set Character set means that the characters and symbols that a C program can understand and accept. These are grouped from the commands, expressions, words, co-statements and other tokens for C language. Character set is the combination of alphabet, digit, special characters and white space. EXAMPLE= ,..,/,;,’,[,], and so on. Characterset Letter digit Empty space character Special character
- 6. Keywords and identifiers There are mainly 40 keywords among which 32 are used by many C-compilers. Example= auto, char, break, case, goto, int, return, if, float and many more. “INDENTIFIERS” are some words or name which identify whether it is a constant or variable.
- 7. TOKENS the blank space are called tokens. In c program all the C- statements having keywords, identifiers, constant, strings, operators and special symbols are called c-tokens. For example , some C-tokens used in a c-programing are: Reverse words: float, do, if etc Constant : 300.9, 20.99, -098 etc Strings: “raman”, “2002-03”etc Operators: +,=,-,<> etc Special symbols:{},[],() @, #, $, % etc
- 8. Identifiers Iis a string of alphanumeric characters . They are used to name variables, arrays, functions. It begins with the alphabetic character. Must not contain white space Connot use keyword as identifiers
- 9. keywords Predefined meaning in a language. Auto, do, for, else, new, try, char, int and so on.
- 10. Literal or constant Whose value cannot change during program execution. Commas and blanks spaces cannot be included E.g= 12,1.2,0XF and so on
