class returning member function
Hi, In the following code snippet, if I comment out line b, the output becomes: constructor constructor whereas if I comment out line c, the output becomes: constructor copy constructor Any explanations regarding what is causing this difference is appreciated. #include <iostream> using namespac... 28 Dec 2007 14:05

Comparing a Vector with Another Vector or a Single Value
Consider a function that compares a vector of doubles, for instance, with either another vector of equal length or just a single double. The type of comparison is not known until runtime. The output will be a vector of bools. Case 1: For each element in vectorA, if vectorA[x] is greater than vectorB[x], output[x... 1 Jan 2008 12:26

Legality Of Superfluous Keywords In Declarations
Hi All, While musing about the probability that rabbit might have been served more often than turkey during the holidays of years long past, I accidentally typed the following declaration into Visual Studio 2005 and hit the compile key. unsigned int long int POLYID; It compiles without error. So I tried.... 7 Jan 2008 11:10

searching for a value in std::map
Hi, I have a map<int,unsigned int>. At a certain point in my program, I know a value that is stored in the map and I need to find the key. I thought I remembered seeing a member function in std::map that did that. Is there? Or am I thinking of a different container class? Thanks, Jim -- [ See http:... 28 Dec 2007 10:37

dynamically loading classes at runtime - will it ever be official?
