C | Dynamic Memory Allocation | Question 8
Consider the following program, where are i, j and k are stored in memory?
(A) i, j and *k are stored in stack segment
(B) i and j are stored in stack segment. *k is stored on heap.
(C) i is stored in BSS part of data segment, j is stored in stack segment. *k is stored on heap.
(D) j is stored in BSS part of data segment, i is stored in stack segment. *k is stored on heap.
Explanation: i is global variable and it is uninitialized so it is stored on BSS part of Data Segment (http://en.wikipedia.org/wiki/.bss)
j is local in main() so it is stored in stack frame (http://en.wikipedia.org/wiki/Call_stack)
*k is dynamically allocated so it is stored on Heap Segment.
