   Question No: 27 ( Marks: 2 )
   What is Software Testing?
   Answer:- (Page 192)
   To understand the concept of software testing correctly, we need to understand a few related concepts.
   Question No: 28 ( Marks: 2 )
   Write unit testing qualitative benefits.
   Answer:- (Page 207)
   Assessment-oriented: Writing the unit test forces us to deal with design issues – cohesion, coupling.
   Confidence-building: We know what works at an early stage. Also easier to change when it’s easy to retest.
   Question No: 29 ( Marks: 2 )
   Where Term Compute can be used in Methods?
   Answer:- (Page 152)
   The term compute can be used in methods where something is computed.
   valueSet.computeAverage(); matrix.computeInverse()
   Question No: 30 ( Marks: 2 )
   Which of the following is a/are non-functional requirement of an e-learning system?
   (a) User friendliness
   (b) Time taken to download study materials through the system should not be too long.
   (c) On-line assignment submission facility
   (d) On-line chatting facility
   (e) Robustness
   Answer:-
   (a) User friendliness
   Question No: 31 ( Marks: 3 )
   Write unit testing principles.
   Answer:-(Page 207)
    In unit testing, developers test their own code units (modules, classes, etc.) during implementation.
    Normal and boundary inputs against expected results are tested.
    Thus unit testing is a great way to test an API.
   Question No: 32 ( Marks: 3 )
   The use of do…. while loops should be avoided. Explain why ?
   Answer:-(Page 159)
   The use of do…. While loops should be avoided. There are two reasons for this. First is that the construct is
   superfluous; Any statement that can be written as a do…. while loop can equally well be written as a while loop
   or a for loop. Complexity is reduced by minimizing the number of constructs being used. The other reason is of
   readability. A loop with the conditional part at the end is more difficult to read than one with the conditional at
   the top.
   Question No: 33 ( Marks: 3 )
   Give 3 Equivalence partitioning guidelines
   Answer:-(Page 199)
    Organize your equivalence classes. Write them in some order, use some template, sequence, or group
   them based on their similarities or distinctions. These partitions can be hierarchical or organized in any
   other manner.
    Boundary conditions: determine boundary conditions. For example, adding in an empty linked list,
   adding after the last element, adding before the first element, etc.
    You should not forget invalid inputs that a user can give to a system. For example, widgets on a GUI,
   numeric instead of alphabets, etc.
   Question No: 34 ( Marks: 5 )
   Discus the symptoms and an exam
   int nState = 10;
   int ZeroArray (int *pArray)
   {
   for (inti=0;i<100;++i)
   pArray[i] = 0;
   }
   Question No: 35 ( Marks: 5 )
   Write at leas 5 General Naming conventions for C++ or Java
   Answer:-(Page 150)
   1. Names representing types must be nouns and written in mixed case starting with upper case.
   Line, FilePrefix
   2. Variable names must be in mixed case starting with lower case.
   line, filePrefix
   3. Names representing constants must be all uppercase using underscore to separate words.
   MAX_ITERATIONS, COLOR_RED
   4. Names representing methods and functions should be verbs and written in mixed case starting with lower
   case.
   getName(), computeTotalWidth()
   5. Names representing template types in C++ should be a single uppercase letter.
   template
   template
   Question No: 36 ( Marks: 5 )
   Explain at least 2 code structures.
   Answer:-(Page 201)
   Case:-
   In Case statement, control can take either of several branches (as opposed to only two in If statement.) First
   node represents the switch statement (C/C++) and nodes in middle correspond to all different cases. Program
   can take one branch and result into the same instruction.
   While
   A while loop structure consists of a loop guard instruction through which the iteration in the loop is controlled.
   The control keeps iterating in the loop as long as the loop guard condition is true. It branches to the last
   instruction when it becomes false.
