Program:To find factorial of a number using recursion

Tweet

When a function calls itself repeatedly, until some specified condition is met then this process is process is called as recursion.Lets have a program to find the factorial using recursion in c++.

CODE:

#include<iostream.h>
#include<conio.h> 
void main() 
{ 
Clrscr();
int fact(int); 
int f,n; 
cout<<"Enter the value to find factorial "; 
cin>>n; 
f=fact(n); 
cout<<"Factorial is "<<f<<endl; 
getch(); 
} 
int fact (int n) 
{ 
int value=1; 
if (n==1) 
return value;      // Base Case
else 
{ 
value=n*fact(n-1);   // General Case- Calls the function itself  
return value;            
}}
