In this article we will be discussing how we can quickly merge two sorted arrays using std::merge() function in C++ STL.So, before solving the problem let's first discuss the std::merge() in C++ STL.What is std::merge()?std::merge() function is an inbuilt function in C++ STL, which is defined in the header file. merge() is used to merge two sorted ranges or series. This function combines two sorted ranges to make one single sorted range. All the elements are compared using less than operator (

In this article we will be discussing the working, syntax and examples of quick_exit() function in C++ STL.What is quick_exit()?quick_exit() function is an inbuilt function in C++ STL, which is defined in the header file. quick_exit() function is used to quickly terminate the calling process means it terminates the process without cleaning of its resources.This function is used for normal termination and no additional cleanup tasks are being performed like, no object destructors are called, whereas the C streams are closed or flushed, the files which are opened with tmpfile are being removed.When we terminate a process using quick_exit() ...
