Processes line up in the ready queue as they arrive. Ready queue: A queue of all processes that are waiting to be scheduled to run on the CPU. Thus, schedulers may decide to swap out idle processes from memory onto the disk to temporarily free up space for other processes. Suspension: A computer has a limited amount of main memory. Those resources are usually a computer’s CPU and main memory. Scheduler: A special system program that manages the allocation of resources to processes. (std::exit then destroys static objects and terminates the program).Before proceeding, make sure you understand the following terms: ĥ) Execution of the return (or the implicit return upon reaching the end of main) is equivalent to first leaving the function normally (which destroys the objects with automatic storage duration) and then calling std::exit with the same argument as the argument of the return. In place of void we can also use int return type of main() function, at that time main() return integer type value.ġ) It cannot be used anywhere in the programĪ) in particular, it cannot be called recursivelyĢ) It cannot be predefined and cannot be overloaded: effectively, the name main in the global namespace is reserved for functions (although it can be used to name classes, namespaces, enumerations, and any entity in a non-global namespace, except that a function called "main" cannot be declared with C language linkage in any namespace).ģ) It cannot be defined as deleted or (since C++11) declared with C language linkage, constexpr (since C++11), consteval (since C++20), inline, or static.Ĥ) The body of the main function does not need to contain the return statement: if control reaches the end of main without encountering a return statement, the effect is that of executing return 0. Main main is a name of function which is predefined function in C++ library.
