How many base cases are in the functionabove?
a. 0
b. 1
c. 2
d. 3
int func2(int m, int n) {
if (n == 0)
return 0;
else
return m + func2(m, n-1);
}

The answer is (b). 1.

Explanation:

In the code there is only 1 base case .

the base case is as following:-

if(n==0)

return 0;

this is the base case.

Base case is the most important statement in the function that uses recursion because without base case the recursion calls will keep on going and we will get a run time error.
