Which of the following statements are CORRECT?

1) Static allocation of all data areas by a compiler makes it impossible to implement recursion.

2) Automatic garbage collection is essential to implement recursion.

3) Dynamic allocation of activation records is essential to implement recursion. 4) Both heap and stack are essential to implement recursion.

Option A. 1 and 2 only
Option B. 2 and 3 only
Option C. 3 and 4 only
Option D. 1 and 3 only
True Answer D

Explanation :

To implement recursion, activation record should be implemented by providing dynamic memory allocation. This dynamic allocation is done from runtime stack. Heap is essential to allocate memory for data structures at run-time, not for recursion. So, statement 1 and 3 are correction.

Which of the following statements are CORRECT?

1) Static allocation of all data areas by a compiler makes it impossible to implement recursion.

2) Automatic garbage collection is essential to implement recursion.

3) Dynamic allocation of activation records is essential to implement recursion. 4) Both heap and stack are essential to implement recursion.

Consider the C function given below
int f(int j)
{
static int i = 50;
int k;
if (i == j)
{
printf(“something”);
k = f(i);
return 0;
}
else return 0;
}
Which one of the following is TRUE?

Option A. The function returns 0 for all values of j.
Option B. The function prints the string something for all values of j.
Option C. The function returns 0 when j = 50.
Option D. The function will exhaust the runtime stack or run into an infinite loop when j = 50.
True Answer D

Explanation :

 For any value of ‘j’ other than 50 the function will return 0, for j=50, then condition (i==j) will be true, it will print “something” and function will be called recursively with same value till the run time stack overflows.

Consider the C function given below
int f(int j)
{
static int i = 50;
int k;
if (i == j)
{
printf(“something”);
k = f(i);
return 0;
}
else return 0;
}
