Write a program to find the factorial of a given number using recursion function

/*program to show the factorial of any number which is inputed by the user by recurtion*/

void main()

{

int a;long int c=1,f;

clrscr();

printf("Enter any number to know its factorial ");

scanf("%d",&a);

f=fact(a,1,c);

printf("\nFactorial of %d is %ld ",a,f);

getch();

}

fact(int a,int b,long int c)

{

if(b<=a)

{

c=c*b;

return fact(a,(b+1),c);

}

return c;

}

Output

Enter any number to know its factorial 5

Factorial of 5 is 120
