phases in SDLC
The phases may be diffred for different SDLC models.
some of the SDLC are
waterfall model(all requirements must be collected in the
first phase itself)
spiral model(processing looks like a spiral fashion,the
desired requirements can be added in next level spirals)
incremental model
prototype model
Stack and queue are data structures. stack is referred as
Last In First Out(LIFO), uses a single pointer
queue is First In First Out(FIFO), uses 2 pointers , one
for insertion and another for deletion.
stack is used for all arithmatic operations, eg. polynomial
addition.
