What is the difference between malloc() and calloc() functions?
Correct Answer
As against malloc(), calloc() needs two arguments, the number of elements to be allocated and the size of each element For example, p = (int *) calloc (10, sizeof (int)); would allocate space for a 10- integer array Additionally, calloc() would also set each of this element with a value 0 Thus the above call to calloc() is equivalent to: p = (int *) malloc (10 * sizeof (int)); memset (p, 0, 10 * sizeof( int ));
