Zero factorial equal one

Question

In some tests, this well-known fact is ignored. For example:
Fill in the blanks to get a function calculating factorial:
int fact(int n) {
if (n==__)
return 1;
return __*fact(__-1);
}
If the first blank I write 1, answer will be accepted as correct. But then one case (0!) is lost

Answer 1

Yes it's what I was mean. I've already used report for this quiz question, hope sololearn fix it🤔

Answer 2

Fill in the blanks to get a function calculating factorial:
int fact(int n) {
if (n==0)
return 1;
return n*fact(n-1);
}
when you write n == 0 it will return 1. How can you say 0! lost.
If the first blank I write 1, answer will be accepted as correct. But then one case (0!) is lost
