The basic operation of an array is: Traversal Insertion Deletion Searching Sorting Merging Find min and max Find Duplicate element Find 2nd largest number Matrix operation

What is the requirement of an array? To overcome the disadvantages of variable we will use array . What is the disadvantages of variable ? The disadvantages of array is variable cant not hold multiple value at a time , means one variable can hold only one value at a time . What is Array?

Types Of Recursion: Direct Recursion Indirect recursion Tail Recursion Non-Tail Recursion Linear and Tree Recursion 1.Direct Recursion: If a function calls the same function again is called as direct recursion . int fun(){ //Statement fun(); } Code: #include<stdio.h> int fun(int n){ if(n==0) { return n; }  printf(“%dn”,n);  return fun(n-1); } int main() { fun(5); return

Fibonacci: Fibonacci Series is the pattern of numbers where result is calculated based on the addition of previous two terms . Code: #include<stdio.h> int fib(int n) { if(n<=1) { return n; } return fib(n-1)+fib(n-2); } int main() { int result; result=fib(3); printf(“the result is %d”,result); return 0; } Output: the result is 2

Defination: A function calls itself is called recursion . Find out the factorial of a number using recursion : Factorial: In mathematics , the factorial of a non-negative integer n , is denoted by n ! . The factorial of a number is the multiplication of all the integer from n to 1 . Code:

With argument with return type(WAWR): A “with argument, with return type” function is a type of function in programming that takes one or more arguments as input and returns a value upon execution. Here’s the definition syntax for a with argument, with return type function in C: return_type function_name(data_type parameter1, data_type parameter2, …) { //

With argument no return type(WANR): A “with argument, no return type” function is a type of function in programming that takes one or more arguments as input but does not return any value upon execution. Here’s the definition syntax for a with argument, no return type function in C: void function_name(data_type parameter1, data_type parameter2, …)

No argument with return type(NAWR): A “no argument with return type” function is a type of function in programming that does not take any arguments but returns a value upon execution. Here’s the definition syntax for a no argument with return type function in C: return_type function_name() { // Function body – code block where

No argument no return type(NANR): A “no argument, no return type” function, also known as a void function with no parameters, is a type of function in programming that does not take any arguments and does not return any value. Here’s the definition syntax for a no argument no return type function in C: void

Types Of Function: There are 2 types of functions are present . Predefined function [Build in function] User Defined Function What is pre-defined function ? Those functions which are already available in c language such type of functions are known as predefined function . Predefined function means we can call those functions directly . EX:-
