Find factorial using recursion in C++

Here we will write a C++ program to find factorial using recursion, first we will understand what are factorials of a number and how to find out the factorials of a number.

Lets start with what is factorial.

What is Factorial of a number:

The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example,

Factorial of 5,   5!= 5 x 4 x 3 x 2 x 1 = 120

Now we will write a program to find factorial using recursion in C++.

Program to implement Linear Search C++

Here we will write a program to implement Linear Search C++ programming language, so first lets start with what is linear search and how to write a program to implement linear search in C++.

 

What is Linear Search:

Linear search or sequential search is a method for finding a target value within a list. It sequentially checks each element of the list for the target value until a match is found or until all the elements have been searched

Linear search runs in at worst linear time and makes at most n comparisons, where n is the length of the list. the average time it takes is n/2, where n is the number of elements in the list/series/sequence.

Now lets write the C++ code to implement Linear search:

Performing Linear Search C++ Code:

C++ Program to find factorial of a Number

What is Factorial of a number?

Factorial of a number ‘n’ is the product of all positive integers less than or equal to n, denoted by ‘n!’. For example find factorial of 5.

Now let’s see the program to find factorial of a number in C++
