Correct answer: (A)
has a structured English equivalent representation

202. Select statements from the following list which may be used in structured English

  1. if marks are too low fail student
  2. if marks >=60 enter first class
  3. if average height select candidate
  4. if weight < 40 kg. reject candidate
  1. i and ii
  2. ii and iii
  3. iii and iv
  4. ii and iv
Correct answer: (D)
ii and iv

203. Structured English description of processes

  1. should be understandable to a user of a computer based system
  2. should be understandable to a programmer
  3. can be descriptive in nature
  4. should be translatable by a compiler
  1. i and iii
  2. ii and iv
  3. i, ii and iv
  4. i and ii
Correct answer: (D)
i and ii

204. Structured English statements must be

  1. short and clear
  2. specified quantitatively
  3. specified qualitatively
  4. detailed and descriptive
Correct answer: (B)
specified quantitatively

205. An extended entry decision table has

  1. only Y, N or - entries
  2. entries which extend the condition
  3. questions asked extended into the condition entry part of the table
  4. only numerical entries
Correct answer: (C)
questions asked extended into the condition entry part of the table

206. In a limited entry decision table the condition entries may be

  1. Y or N only
  2. Y, N or -
  3. A binary digit
  4. Any integer
Correct answer: (B)
Y, N or -

207. A X against an action in an action row signifies that the

  1. action is not to be taken
  2. action is to be taken
  3. action is important
  4. action is not important
Correct answer: (B)
action is to be taken

208. In a limited entry decision table the condition stub

  1. lists X or - corresponding to actions to be executed
  2. lists the conditions to be tested
  3. has Y or N or - entries
  4. lists the actions to be taken
Correct answer: (B)
lists the conditions to be tested

209. The conditions in the condition stub of a limited entry decision table

  1. must be in sequential order
  2. must be in the order in which they are to be tested
  3. may be in any order
  4. must be in the order in which they are to be executed
Correct answer: (C)
may be in any order

210. The following while structure is wrong because
balance =500
while balance <=1000 do
Write (amount due - balance)
Read next record
end while

  1. read must appear before write
  2. this loop will never terminate
  3. no read allowed in a loop the contents of next record is not known
Correct answer: (B)
