I\'d like to implement a sequence container with the bells and whistles required for an STL class - for example, my own deque class that can use all of the STL algorithms and utilities that the nor开发
Can we have a function pointer which points to a function which use a varying argument list? For example, lets say i need to select a function among a number of functions based on some input T \'inpu
I have a dilemma of whether to have a multimap <int key, int value> or maintain a vector containing a vector of all values corresponding to int key.
I\'m quite familiar with the STL and how to use it.My question is... If I were to implement my own开发者_运维百科 STL container type, how are the internal iterators defined? STL classes tend to have
If i have a myVector which is a STL vector and execute a loop like this: for(int i=0;i<myVector.size();++i) { ... }
Can anyone please tell me that when do we prefer multimap开发者_开发百科 over map?You\'d use a multimap when you want to allow the same key values in your map.
In the following snippet of code, I\'ve overloaded the operator== to compare my 开发者_JAVA技巧pair type with string.But for some reason, the compiler isn\'t finding my operator as a match for the fin
After calling std::regex_search, I\'m only able to get the first string result from the std::smatch for some reason:
when insert new element to list/map, it returns the iterator pointed to the newly added element. But if insert failed, what does list/map return? I have read the referen开发者_开发百科ces, when failed
This question already has answers here: Is it better to use std::memcpy() or 开发者_运维知识库std::copy() in terms to performance?
