Question Total

Marks What are Design Patterns? Explain them briefly.

i- Consider the following Code Segment: (10) · Input: sequence of numbers, size, number · Variable: count=0 · Do while (end of sequence) · If (sequence[i] == prime Number) · Count = count++ · Else · Count = count to · END IF · END DO · If (count == size) · “sequence of number is a prime number sequence” · if (count is odd) · aÅ finalMax(sequence) · yÅ a X number · else · aÅ finalMin(sequence) · yÅ a X number · display y · else · “sequence of number is not a prime number sequence” · END IF · END PROGRAM

Draw the Flow Graph for the Code Segment. Find Cyclomatic Complexity of the Flow Graph.

(HINT: for the above code segment, ignore any syntax or grammatical errors.)

ii- what is Black Box and White Box Testing. Describe briefly. (5)

Following is the prototype of a function to find the index of the minimum value in an array.

int min(int array[ ], int arraySize);

(a) Identify equivalence partitions to devise black-box test cases for this function. (5 Pts)

(b) Write test cases against each partition identified in part (a). (5 Pts)

What are Boolean Bugs? Describe briefly. What are symptoms of Boolean Bugs?

What is Software Architecture? What is its importance? Describe briefly.
