The phases of SDLC are:
**Communication.
**Requirements gathering
**Analysis
**Implementation
**Testing
**Maintainance
Differance between stack and queue..
Stack follows LIFO structure i.e -> last in first out.
the element which enters last exits first..
Queue follows FIFO structure. i.e -> first in first out.
the element which enters first exits first..
USE OF STACK:
with refrance to C, we use stack wiht the program counter.
i.e when we jump to a function, we store the address to
return to on a stack..
u can understand this in more detail if you study teh
actual flow of program while calling functions.
