Unexpected output for large inputs in fibonacci program

#1

I understood as to why the program is not working when we’re inputting the same value as the size of the array. The array will go out of bound but when I entered another value like 98 I’m getting a negative output. Why is this happening?

#2

Fibonacci 98th is very large value it overflows the long long int too. That’s why you are getting negative output.
