I\'m using the hash_map in C++ and want to supply a simplified type name for it: The key type and hasher function are always the same.
What is the most elegant way to determine if a call to std::sort(begin, end) actually modified the range?
I wa开发者_JAVA技巧nt to pass an rvalue through std::bind to a function that takes an rvalue reference in C++0x.I can\'t figure out how to do it.For example:
I have some code that, in its smallest complete form that exhibits the problem (being a good citizen when it comes to asking questions), basically boils down to the following:
in C# you have to declare everything in a class so an example factory pattern could look like: namespace MySpace {
So having: struct A { void foo(int) { } }; typedef std::function<void(int)>开发者_JAVA技巧Function;
is this code ok? void SomeClass :: foo(const char * _name) { //name is of type const char * name = std::string(开发者_如何学运维_name).c_str();
If I have fo开发者_开发百科r example the following statements: char f_name[11]; std::cin.getline(f_name,10);
I have heard using namespace std; is bad practice, and that I should use std::cout and std::cin directly instead.
Imagine a std:vector, say, with 100 things on it (0 to 99) currently. You are treating it as a loop. So the 105th item is index 4; forward 7 from index 98 is 5.
