 Write a Factorial Program using Recursion in C++

What are recursive functions?

<!-w3school-> Recursive functions are those functions that repeatedly calls itself directly or indirectly during execution .
                          

                                          Steps to write the program

1. Open a turbo c++ compiler or any other compiler.

2. Write the code given below .

#include<iostream.h>

#include<conio.h>

int Factorial(int x)  // Factorial Function  Coding

{

 if(x<=1)

 { return 1; }

 else {  return x*Factorial(x-1); }

}

void main()      // Main Function Coding

{

clrscr();

int n;

cout<<"\nEnter the value of n";

cin>>n;

cout<<"\nThe factorial of the number    "<<n<<"is equal to   " <<Factorial(n);

getch();

}

OUTPUT:
