The size can be calculated using thesizeof operator, which returns the total memory occupied by the array in bytes. To determine the number of elements, you can divide the total size of the array by the size of a single element. Syntax: sizeof(arrayName) / sizeof(arrayName[0]) Here,...

While smaller is generally better, a rule of thumb is to stick to lookup tables that are <= 4096 bytes in size. As an upper limit: if your lookup table is larger than 64K it's probably worth reconsidering. Constructing a table So we've figured out that we can create a small table....
When you define variables that overlap in the marker address area, in this example a string and an array of bytes, it is like a union in C. You can put a string into the string variable and then each character can be pulled out from the overlapping byte array. ...
Figure 1shows a complete sample code snippet for producing a safe array of bytes in C++ using CComSafeArray. The code is part of a hypothetical COM method; however, the same CComSafeArray-based code can be used for C-interface DLL boundary functions, as well. ...
