not be executed

execute until all conditions match

execute infinitely

obtain progressive approach

Discuss

Answer: (c).execute infinitely

Q28.

Infinite recursion leads to ...............

Q29.

Recursion is memory-intensive because:

Recursive functions tend to declare many local variables

Many copies of the function code are created

It requires large data values

Discuss

Answer: (b).Previous function calls are still open when the function calls itself and the activation records of these previous calls still occupy space on the call stack
