Question

Consider the following statements :
$S_1$ : While program in execution, access to heap memory is slower as compared to accessing variables allocated on stack.
$S_2$ : While program in execution, in a multithread situation, each thread has its own stack and share a common heap memory.
$S_3$ : During a program execution, heap is stored in main memory and stack is present in secondary memory.
Which of the above is incorrect ?

• A. Only $S_2$ and $S_3$
• B. Only $S_1$ and $S_2$
• C. All of these
• D. Only $S_3$

Answer 1

The correct option is D Only $S_3$

$\bullet$ Statement $S_1$ and $S_2$ are correct.
$\bullet$ Statement $S_3$ is incorrect. Heap and stack both are present in main memory.
