Question

Which of the following functions allocates multiple blocks of memory, each block of the same size?

I had been asked this question in a job interview.

My question is from DMA Functions, Memory Leak, Dangling Pointers in section Dynamic Memory Allocation in C of C

Answer 1

Correct option is (c) calloc()

The best explanation: malloc() allocates a single block of memory whereas calloc() allocates multiple blocks of memory, each block with the same size.
