Question

Consider the following definition of the recursive function print. void print(int num)
{
$\quad$If (num > 0)
$\quad${
$\quad$$\quad$Cout << num << " ";
$\quad$$\quad$Print(num - 1);
$\quad$}
}
What is the output of the following statement?
Print(4);
A) 0 1 2 3 4
B) 1 2 3 4
C) 4 3 2 1
D) 4 3 2 1 0

Quizplus · Accepted Answer

The function print(num) recursively calls itself with num-1 until the base case of num<=0 is reached. Therefore, the output will be 4 3 2 1 since the function starts with num=4 and decreases by 1 in each recursive call until the base case is reached.
