What does the following function do?
C
int fun(int x, int y)
{
if (y == 0) return 0;
return (x + fun(x, y-1));
}
|
(A)
x + y
(B)
x + x*y
(C)
x*y
(D)
xy
Answer: (C)
Explanation:
int fun(int x, int y): This function is a recursive function that calculates the product of two integers x and y. It does this by repeatedly adding x to itself y times. If y is 0, the function returns 0 (base case). Otherwise, it returns x plus the result of calling itself with x and y-1.
Therefore, The function adds x to itself y times which is x*y.
Hence (C) is the correct answer.
