int ctr=0;
printf(“enter any no\n”);
scanf(“%d”&n);
for(i=1;<=n;i++)
{
if(n%i==0)
{
ctr++;
}
}
if(ctr==2)
{
printf(“%d is prime no\n”);
}
else
else
{
printf(“%d is not a prime no\n”);
}

}
write a recursive function for n
write a recursive function for n
Output:
1. Enter the number : 5 Factorial of number: 120
2. Enter the number : 3 Factorial of number: 6
3. Enter the number : 9 Factorial of number: -30336
Conclusion: the program is error free
VIVA QUESTIONS:
1) What is the meaning of factorial number?
Ans : Factorial of a number is nothing but the multiplication of numbers from
a given number to 1
2) What is the meaning of recusive function ?
Ans: A function call it self is called recursive function
3) Define library functions ?
Ans: The functions have already been written, compiled and placed in libraries and are called library functions.
4) Define formal parameters ?
Ans: Formal parameters are the parameters given in the function declaration as function definition.
long double fact(int n)
{
if(n>0)

printf("enter any +ve integer (or) 0\n");
scanf("%d",&n);
