6:       return num * Fact(num-1);
7: }

Which of these lines are the General Case?

3
→Incorrect
4
→Incorrect
5
→Incorrect
6
→Correct

4. Look at this sample code: 

1: public int Fact(int num)
2: {

4
→Correct
5
→Incorrect
6
→Incorrect

5. Look at this sample code: 

 1: public int Fact(int num)
 2: {
 3:   if (num == 0)
 4:       return 1;
 5:   else
 6:       return num * Fact(num-1);
 7: }
