Sometimes you need to clear all the members of a struct after it was used. With large structs, you usually use memset() for that purpose. However, for smaller structs that
In earlier stages of C++, it was impossible to delete a const object, even if that object was constructed on the free store. This could cause memory leaks. However, the
While most of the code optimizations are performed at compile time, there are optimizations that only a linker can perform. For example, it can detect unreferenced function calls. These are
To initialize a struct that contains bit fields, simply use the ={0}partial initialization list: int main(){ struct MP3_HEADER { unsigned Sync:11; unsigned Version:2; unsigned Layer:2; unsigned Protection:1; unsigned Bitrate:4; unsigned
Question: Does Java have a switch statement that can use doubles and floats? Answer: The Java switch statement only supports values of type char, byte,short, or int. To conditionally execute
Most C++ users already know that they shouldn’t use auto_ptr objects as elements of STL containers. However, fewer users know exactly why this is so. The C++ Standard says that
I often hear people ask whether it’s possible to write code that is quicker than STL. This is a paradoxical question: the C++ Standard defines minimum performance requirements with which
Question: I have a listbox with some names loaded from a recordset, I have also associated the memberID with its associated name as in the following: lstMember.ItemData(lstMember.NewIndex)= rsMembers![MemberId]. I want
