Array: Is the space to store the same type of data in memory continuouslyBecause you need to store large amounts of data of the same type in real-world applications, you have an arrayDefinition of array: data type [] array name =new data type [length];Example: int [] a = new int [10];data type [] array name =new data type []{value, separated by commas};Example: int [] b = new int []{1,2,3,4,5};Array assignment and value: use subscript to manipulate each element in the arrayAssignment: array name
Consider the following code:class widget{public: ... ~widget () {...} // Suppose this might spit out an anomaly . }; void dosomething () { std::vectorv; } // V is destroyed here .When Vector v is destroyed, it is responsible for destroying all the widgets it contains. Suppose V contains 10 widgets, and during the first element of the destructor, an exception is thrown. The other nine widgets should still be destroyed, so v should call each of their destructors. Suppose that during a call, th

We try to ensure that only shared data is locked and data is processed outside of the locked range. Do not perform I/O operations in the case of locking mutexes, because I/O operations are slow. You can call Std::unique_lock's unlock () operation to release the mutex if necessary, and then call Lock () when needed to lock the mutex.void Get_and_process_data () { std::unique_lockIn the
