Program to calculate the factorial of a number. Use the concept of recursion instead of using loops.

#include

void main()

{

int a, fact;


printf("\nEnter any number: ");

scanf ("%d", &a);

fact=rec (a);

printf("\nFactorial Value = %d", fact);

}

rec (int x)

{

int f;


if (x==1)

return (1);

else

f=x*rec(x-1);


return (f);

}
