• CMPS 12A write a C program that operates in the

• write a C program that operates in the same way,
  i.e. same prompts, same input and same output.
  However, therequirements for this program are
  relaxed somewhat from those in pa3 in that it is
  not necessary to filter out all types of bad
  input. Design your program to respond to string
  inputs by printingPlease enter a positive
  integer as specified in pa3, then scan for
  another integer. Respond similarly to integer
  input that is negative orzero. It is not
  necessary to react to double inputs according to
  the pa3 specifications however. Thus you may
  assume that things like 25.78 will not be used
  as input to your program. Everything you need to
  dothis was explained in the lab7 project
  description. In particular, review the
  explanation of the scanf()function given in that
  document before you begin this program.

• In order to implement a DBMS, there must exist a
  set of rules which state how thedatabase system
  will behave. For instance, somewhere in the DBMS
  must be a set ofstatements which indicate than
  when someone inserts data into a row of a
  relation, ithas the effect which the user
  expects. One way to specify this is to use words
  to writean essay' as to how the DBMS will
  operate, but words tend to be imprecise and open

  are more usually defined using RelationalAlgebra.
