Tokens in C++

This is the presentation on tokens done by me and my friends as a team.

1. Presented by Divya Sree Rayshini Issac Mahender TOKENS

2. Tokens are the basic building blocks in C++ language. The smallest individual units in a program are known as tokens. A program is constructed using a combination of these tokens. TOKENS

5. Definition: Sequence of characters that have a fixed meaning . Keywords must be written in lower case. Reserved identifiers and can’t be used as names for the program variables user-defined program elements. KEY WORDS Examples: int , float, char, double, switch, break, char, const , Continue, default, for, if, goto , static, void, sizeof , while, return, int , long, do, while etc…

7. Definition: A variable is a quantity whose value may change during the program execution. Examples: int a, char choice, etc ., VARIABLES

8. Naming Conventions: A variable name should contain alphabets (a-z , A-Z) and digits (0-9). not start with a number or a digit. not be a keyword. case sensitive.

11. CONSTANTS Definition : The quantities whose value do not change during the program execution are known as constants.

13. Definition: A group of characters that are treated as a single data item enclosed in double quotes are known as strings. General syntax: char string-name[size]; size determines the number of characters in the string name. Example: char city[9]=“New York”; STRINGS

15. Definition: An operator is a symbol that performs operations on one or more operants. There are 8 types of operators supported by C ++ language . OPERATORS

16. Arithmetic operators (+,-,*,/,%) Relational operators (==,!=,<,>,<=,>=) Logical operators (||,&&,!) Conditional operators (? :) Assignment operators (=,+=,-=,/=,*=,%=,) Increment /decrement operators (++,--) Bitwise operators (&,|,^,<<,>>,~) Miscellaneous/special operators (sizeof,*,->) EIGHT TYPES OF OPERATORS
