On a very high-level, STL library has lot of containers that are often used, and it has few methods that could be applied on those containers. Basically STL has several ready-to-use common classes that you can use in your C++ programming. We’ll cover STL in detail probably in a separ...
is left. The main reason to utilizelock_guardinstead of directly using thelockandunlockmember functions is to guarantee that themutexwill be unlocked in all code paths even if the exceptions are raised. So, our code example too will use the latter method to demonstrate the usage ofstd::...
an aggravation of OOP, which means also the STL containers, is that it is not always cheap to allocate and deallocate small temporary objects. You can mitigate this in your code with some memory management of your own, such as having the temporary become a private class variable that can be...
Use the std::copy Algorithm to Print a String The copy method is from the <algorithm> STL library, and it can manipulate the range elements in multiple ways. Since we can access the string container itself as a range, we can output each element by adding the std::ostream_iterator<char>...
In general, you will want to support both the Collections and Generic interfaces so that clients currently using the Collections interfaces will be able to use your types. Here is how you might declare support for both: template <class T> ref class vector : System::Collections::ICollection...
适配器模式简介(Introduction to Adapter Pattern) 适配器模式主要用于解决两个已有接口不兼容但需要一起工作的问题。它是一种结构型设计模式,目的是使得原本由于接口不兼容而不能一起工作的那些类可以一起工作。 如何实现适配器模式(How to Implement Adapter Pattern) ...

With the release of macOS Sonoma, Apple has also updated the current versions of Metal developer tools for use in Windows. Here's how to get and use them.
The general rule of thumb to avoid such headaches is to not use more than one x++ or ++x in a single operation. So, if we pad our macros and we don't mix it with x++ or ++x, are we actually safe? The answer is, unfortunately, no. The most evil macro of all The worst ...
Modern C++ has a lot of useful functions thanks to its evolution from the C language. One of them was thegets()function that we use to get string inputs and that we were able to use in C++11 or earlier. In C++14, thegetsfunction was removed, whilefgetsor other input functions remain...
