An abstract data type (ADT) is an abstraction of a data structure. An ADT specifies the type of data stored and the different operations you can perform on it. Eric Roberts. CS 106B. February 4, 2013. The Allocation of Memory to Variables. When you declare a variable in a program, C++ allocates space for that variable from one of several memory regions.. One region of memory is reserved for variables that persist throughout the lifetime of the program, such as constants. This information is called . x86-64 Procedures, Data. Today.
