Design an integer array class capable of dynamically created memory space CIArrar, use CIArrar classes to create objects, according to the size of the corresponding variable application memory space, used to overcome the basic array constants must be used to create the disadvantages of memory space (such as int a [N]. Here N must be a previously defined constants), an integer array class CIArrar also need to include a function that can change the size of the memory space created

CodePudding user response:

Dynamic array, it is good to use Vector
