Factorial of a Number In C Using Recursion

In this article, we are going to write a program to find Factorial of a Number In C Using Recursion.

To make this program, we will use the following concept given below.

• Function in C
• Recursion in C

If you do not know about these topics well, then you may not understand this program, so you should know about them in detail from the link given above.

Now without wasting time let’s start programming.

Factorial of a Number In C Using Recursion

Algorithm

• Program Start
• Declaring Variable
• Input Number From the user
• Calling Recursive Function
• Display Result Through Printf Function
• Program End

Program

//Factorial of a Number In C Using Recursion

#include<stdio.h>
int fact(int );
void main()
{ //variable declaration
  int x,z;
  
  //input number
  printf("Enter a number : ");
  scanf("%d",&x);
  
  z=fact(x); //calling recursive function to find factorial
  printf("factorial is %d",z);
}
int fact(int n)
{   int ft=1;
    if(n==1)
    return(n);
    ft=n*fact(n-1);
    return(ft);
}

Output

Enter a number : 5
factorial is 120
