Question: The sizeof( ) function doesnâ??t return the size of the block of memory pointed to by a pointer. Why?
Answer: The sizeof( ) operator does not know that malloc( ) has been used to allocate a pointer. sizeof( ) gives us the size of pointer itself. There is no handy way to find out the size of a block allocated by malloc( ). |
