Consider the following C program segment.

while(first <= last) 
{ 
    if (array[middle] < search) 
        first = middle + 1; 
    else if (array[middle] == search) 
              found = TRUE; 
          else last = middle - 1; 
    middle = (first + last)/2; 
}
 if (first > last) notPresent = TRUE; 

The cyclomatic complexity of the program segment is ________.

Which one of the following assertions concerning code inspection and code walk-through is true?

Consider three software items: Program-$$X,$$ Control Flow Diagram of Program-$$Y$$ and Control Flow Diagram of Program-$$Z$$ as shown below

The values of McCabe’s Cyclomatic complexity of Program-$$X,$$ Program-$$Y,$$ and Program-$$Z$$ respectively are

The following figure represents access graphs of two modules $$M1$$ and $$M2.$$ The filled circles represent methods and the unfilled circles represent attributes. If method m is moved to module $$M2$$ keeping the attributes where they are, what can we say about the average cohesion and coupling between modules in the system of two modules?
