explanation of all operators

1)Unary operators:- are those operator which required only one operand(data).

2)Binary operator:- are those operator which required two operand for operation.they are also also five types.

Arithmetic operators:-

also known as conditional expression .used ?: symbol
syntax:- (if condition is true)?then value X else: value Y

Bitwise operator:- it is of 6 types
Relational operator:-it is also 6 type
Logical operator:-it is of 3 types
Assignment operator:-it is 5 types

3) Ternary operator :-

also known as conditional expression using ?: symbol

syntax:- (if condition is true)then value is x :otherwise value is Y

example:- x>0?printf("positive"):printf("non positive")

Type casting

type casting or type conversion allows us to convert one data types into another.for type casting cast operator is required. Syntax:-- (type)expression or value; Example: int f =9/4; //without type casting o/p=2 float f=(float)9/4; //with type casting o/p=2.3 Type conversion are of two types: 1)Implicit Type Conversion:- it is also known as automatic type conversion.When the type conversion is performed automatically by the compiler,such type of conversion is known as implicit type conversion. 2)Explicit Type Conversion:- the type conversion performed by the programmer is known as explicit type conversion.which is done by cast operator as above mentioned.

UNION

Definition:- Union is similar to structure, except it allows you to define the variable that share storage spaces.Defining a means creating a new data types. How use union:- when we create a structure by using struct keyword, now making a union we just replace the keyword struct with the keyword union , other syntax will be same. Difference between Structure and Union:- the only difference between them is in memory. NOTE:- union is used for low level programming but structure mostly used for high level programming. Program to access union:- """SHARE IT WITH YOUR FRIENDS IF HE DID NOT KNOW""""

Recursion--

Definition:- when a function call itself is called recursion. note:- the problem which is solved by recursion is also solved by loops, but it is not necessary the problem solved by loops is also solved by recursion. Example:- Explanation:- 1) a fun function declared which takes argument and return value 2) main starts fun is called by passing 3 value 3)after calling fun definition starts, where check if a==1 no because a is 3, s=a+fun(a-1) means s=3+fun(2) from here fun function is again called now this body again execute now a is 2, so s=3+fun(2), fun(2) is replaced by 2+fun(2-1=1) i.e s=3+2+fun(1) again fun function is called... overall s=3+2+1=6, s is return this return value goes where fun function is called , where return value is stored in k, so k=6 now print is 6.
