What is the significance of using a char porinter in #define any_size(any) (char*)(&any)-(char*)((&any)-1) ?Why can't we use any other pointer there?

Dan

• Jun 6th, 2006

A generic method for doing this would betypedef int MyType;MyType *p = 0;return (int) ++p;of course, the ++ operator uses sizeof itself, but this is still a valid answer to an interview question in my opinion.

No, you can’t add pointers together. If you live at 1332 Lakeview Drive, and your neighbor lives at 1364 Lakeview, what’s 1332+1364? It’s a number, but it doesn’t mean anything. If you try to perform this type of calculation with pointers in a C program, your compiler will complain. The only time the addition of pointers might come up is if you try to add a pointer and the difference of two pointers....

As described at the beginning of this chapter, some compilers for PC compatibles use two types of pointers. near pointers are 16 bits long and can address a 64KB range. far pointers are 32 bits long and can address a 1MB range. near pointers operate within a 64KB segment. There’s one segment for function addresses and one segment for data. far pointers have a 16-bit base (the segment address) and...

For example, you want to define a "matrix_multiply" function to get A * B, how to declare the function and how to implement it? Make sure that you consider error handling stuff, e.g., a 2*2 matrix and a 3*3 matrix cannot multiply, and how to detect and deal with the situation when you pass a 3*3 matrix as a parameter which...
