Find Largest Element in Array

31) C PROGRAM TO FIND LARGEST ELEMENT IN AN ARRAY

LOGIC:- Create an array and initialize size of array must be known,because loop is required.now let a variable compare this variable with every element of array if it is larger then value not change if array element is larger than the variable then store the array value in variable . It is doing until the loop is not terminated.

EXAMPLE:-

"""SHARE WITH YOUR FRIENDS"""

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.
