Explain the following with the help of a suitable diagram or an example: – Evaluation stack architecture 5m Dec2005

Explain the following with the help of a suitable diagram or an example.  Evaluation stack architecture 5m Dec2005 A stack is a data structure that implements Last-In-First-Out (LIFO) access policy. You could add an entry of data (or value) to the stack with a PUSH (value) Function and remove an entry of data (or value) from the… Read More »

Explain the following with diagram or example:- Parameter passing using stack in 8086 assembly language 5m Dec2005

Explain the following with the help of a suitable diagram or an example:- Parameter passing using stack in 8086 assembly language 5m Dec2005  Most HLLs use the stack to pass parameters because this method is fairly efficient. To pass parameters on the stack, push them immediately before calling the subroutine. The subroutine then reads this data… Read More »
