Our important application of stacks is in the implementation of recursive procedures in programming languages. The run-time organization for a programming language is the set of data structures used to represent the values of the program variables during program execution. Every language that, like C...
?Maintain the logical distinction between the stack itself, made up of all of its entries (each in a node), and the top of the stack,which is a pointer to a single node. ?Maintain consistency with other data structures and other implementations,where structures are needed to collect several...
