# 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.

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``````

## Conclusion

So friends, in this article, we have written a program to find Factorial of a Number In C Using Recursion.
