Which statement correctly describes calloc() and malloc()?

Options

A. Both always initialize allocated memory to one
B. calloc() initializes allocated memory to zero, while malloc() does not initialize it
C. malloc() always initializes memory to zero, while calloc() does not
D. More than one of the above
E. None of the above

B. calloc() initializes allocated memory to zero, while malloc() does not initialize it

Answer: (B) calloc() initializes allocated memory to zero, while malloc() does not initialize it

The major basic difference between malloc() and calloc() is their initialization behavior.

malloc() allocates a requested amount of memory but does not initialize the contents.

calloc() allocates memory for a number of elements and initializes the allocated bytes to zero.

This distinction is frequently asked in C and C++ programming examinations.
