# C Exercises: Find the Factorial of a number

## C Recursion : Exercise-10 with Solution

Write a program in C to find the Factorial of a number using recursion.
Test Data :
Input a number : 5
Expected Output :

`The Factorial of 5 is : 120 `

C Code:

```#include<stdio.h>
int findFactorial(int);

int main()
{
int n1,f;
printf("\n\n Recursion : Find the Factorial of a number :\n");
printf("-------------------------------------------------\n");
printf(" Input  a number : ");
scanf("%d",&n1);
f=findFactorial(n1);//call the function findFactorial for factorial
printf(" The Factorial of %d is : %d\n\n",n1,f);
return 0;
}

int findFactorial(int n)
{
if(n==1)
return 1;
else
return(n*findFactorial(n-1));// calling the function findFactorial to itself recursively
}
```

Flowchart :

C Practice online:

```#include<stdio.h>
int findFactorial(int);

int main()
{
int n1,f;
printf("\n\n Recursion : Find the Factorial of a number :\n");
printf("-------------------------------------------------\n");
printf(" Input  a number : ");
scanf("%d",&n1);
f=findFactorial(n1);//call the function findFactorial for factorial
printf(" The Factorial of %d is : %d\n\n",n1,f);
return 0;
}

int findFactorial(int n)
{
if(n==1)
return 1;
else
return(n*findFactorial(n-1));// calling the function findFactorial to itself recursively
}
```
