Real-time systems such as those designed to control industrial robots, require timely processing a single processor might be shared between calculations of machine movement, communications, and user interface. In multiprogramming systems, a task runs until it must wait for an external event or until the operating system's scheduler forcibly swaps the running task out of the CPU. In a time-sharing system, multiple human operators use the same processor as if it was dedicated to their use, while behind the scenes the computer is serving many users by multitasking their individual programs. It allows more efficient use of the computer hardware where a program is waiting for some external event such as a user input or an input/output transfer with a peripheral to complete, the central processor can still be used with another program. Multitasking is a common feature of computer operating systems. Even on multiprocessor computers, multitasking allows many more tasks to be run than there are CPUs. Multitasking does not require parallel execution of multiple tasks at exactly the same time instead, it allows more than one task to advance over a given period of time.

This ' context switch' may be initiated at fixed time intervals ( pre-emptive multitasking), or the running program may be coded to signal to the supervisory software when it can be interrupted ( cooperative multitasking). Multitasking automatically interrupts the running program, saving its state (partial results, memory contents and computer register contents) and loading the saved state of another program and transferring control to it. As a result, a computer executes segments of multiple tasks in an interleaved manner, while the tasks share common processing resources such as central processing units (CPUs) and main memory. New tasks can interrupt already started ones before they finish, instead of waiting for them to end. In computing, multitasking is the concurrent execution of multiple tasks (also known as processes) over a certain period of time.

This can be a function pointer or a function object, and defaults to less, which returns the same as applying the less-than operator ( a give priority for a program in mac

Compare A binary predicate that takes two elements (of type T) as arguments and returns a bool. Container Type of the internal underlying container object where the elements are stored.ДЄliased as member type priority_queue::container_type. Template parameters T Type of the elements.ДЄliased as member type priority_queue::value_type. This is done automatically by the container adaptor by automatically calling the algorithm functions make_heap, push_heap and pop_heap when needed. Support of random access iterators is required to keep a heap structure internally at all times. By default, if no container class is specified for a particular priority_queue class instantiation, the standard container vector is used. The standard container classes vector and deque fulfill these requirements.

The container shall be accessible through random access iterators and support the following operations:

The underlying container may be any of the standard container class templates or some other specifically designed container class. Elements are popped from the 'back' of the specific container, which is known as the top of the priority queue. Priority queues are implemented as container adaptors, which are classes that use an encapsulated object of a specific container class as its underlying container, providing a specific set of member functions to access its elements. This context is similar to a heap, where elements can be inserted at any moment, and only the max heap element can be retrieved (the one at the top in the priority queue). Priority queues are a type of container adaptors, specifically designed such that its first element is always the greatest of the elements it contains, according to some strict weak ordering criterion.
