C pointers to arrays — sizes when int is 2 bytes. #include<stdio.h> #include<stdlib.h> #define MAXROW 3 #define MAXCOL 4 int main() { int (p)[MAXCOL]; p = (int ()[MAXCOL]) malloc(MAXROW * sizeof(*p)); printf("%d, %d ", (int) sizeof(p), (int) sizeof(*p)); return 0; } Assume sizeof(int) = 2. What is printed?

Introduction / Context:This question evaluates understanding of pointers to arrays and the difference between the size of a pointer and the size of the pointed-to object. The result depends on platform pointer size and known array dimensions.

Given Data / Assumptions:

• sizeof(int) = 2 bytes.
• p has type pointer to array of MAXCOL (4) ints.
• Classic 16-bit near data pointer size of 2 bytes is assumed.

Concept / Approach:sizeof(p) is the size of the pointer itself (near pointer, 2 bytes). sizeof(*p) is the size of the array it points to, which is 4 * sizeof(int) = 4 * 2 = 8 bytes. The malloc line allocates MAXROW arrays of 4 ints, but the printf only asks for the two sizes.

Step-by-Step Solution:

Verification / Alternative check:On 32-bit systems, the first value would typically be 4, and on 64-bit systems 8, confirming platform dependence for pointer size only.

Why Other Options Are Wrong:

• 4, 16 / 8, 24 / 16, 32: These correspond to different pointer sizes or wrong array-size calculations.

Common Pitfalls:Confusing sizeof(p) with the size of allocated memory or forgetting that *p is an entire array, not a single int.

Final Answer:2, 8
