Question

What is the reason for the uncertainty in the expected time of software failure?

a.

The programmer made errors

b.

The relation between the input and the order of instructions is not known

c.

Both a and b

d.

None of the above

Posted under Software Engineering

Answer: (c).Both a and b Explanation:The reason for the uncertainty in the expected time of software failure is that we do not know where the programmer made errors and the relation between a certain input and the order in which the corresponding set of instructions is being executed is not usually known.
