Question

The number of arguments taken as input which allocating memory dynamically using malloc() is ___________

(a) 0

(b) 1

(c) 2

(d) 3

This question was posed to me in an internship interview.

The question is from DMA Functions, Memory Leak, Dangling Pointers topic in portion Dynamic Memory Allocation in C of C

Answer 1

Correct choice is (b) 1

The best I can explain: An example of memory allocated using malloc():

(int*)malloc(3*sizeof(int)

It is clear from the above example that malloc() takes only one argument as input, that is the number of bytes to be allocated.
