Answer: D) Can't be determined Explanation: We know that a negative value plus a positive value always count backward and the sign depends on the bigger value sign. When you are adding a negative number to a positive number, then the value counts backward and takes the sign of the biggest number.   For example:: Adding -5 and +2 -5 + 2 = -3 (big number is 5 and its sign is '-')   Adding -3 and  +5 +5 + (-3) = 5 - 3 = +2(big number is 5 and it has sign '+').

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 ));
