Software Engineering

In a class definition with 10 methods, to make the class maximally cohesive, number of direct and indirect connections required among the methods are

Consider the following pseudo-code

 I=0; J=0; K=8;
while(I < K-1) //while-1
{
     J=J+1;
     while(J < K) //while-2
     { 
         if(x[I] < x[J])
         {
             temp = x[I];
             x[I]=x[J];
             x[J]=temp;
         }
     }// end of while-2
     I=I+1;
}// end of while-1

The cyclomatic complexity of the above is

What is the defect rate for Six sigma?

What is the availability of the software with the following reliability figures

Mean Time To Repair (MTTR) is 20 hours

Regression testing is primarily related to
