Review Questions
1. Why are McCabe’s cyclomatic number and Halstead’s software science not readily
applicable to object-oriented software?
2. What abstractions are available in object-oriented design to be used as the basis of
object-oriented metrics?
3. When should a metric for a whole system be different than either the sum or the
average of metrics calculated for each class?
4. Is a high LCOM good or bad?
5. Some people have suggested that, in LCOM, just using the difference between the size
of P and Q. That is, the use of the maximum of zero and this difference is not effective.
What would be the effect of this change?
Problems
1. Calculate the Chidamber metrics for the following code that maintains an array of
people/students:
class person{
char* name;
char* ssn;
public:
person(){name = new char[NAMELENGTH]; ssn = new
char[SSNLENGTH];}
~person(){delete name; delete ssn;}
void addName(char* newname){strcpy(name, newname);}
void addSsn(char* newssn){strcpy(ssn, newssn);}
char* getName(){return name;}
void virtual display(){cout
