Q1. Define Logical error and its 3 symptoms?

Logical Errors: A logical error occurs when the code is syntactically correct but does not do what you expect it to do. Symptoms: 1) The code is misbehaving in a way that isn't easily explained. 2) Results are the opposite of what is expected. 3) Output looks strange, but has no obvious symptoms of corruption.

Q2. design pattern given thy unki class btani thi table me 5 marks scenario given tha uska design pattern btana tha and why?

3) Flow notation draw krni thi if loop or case statement ki · 4) what do you know about byte order and give example · Byte Order and Data Exchange

The order in which bytes of one word are stored is hardware dependent. For example in Intel architecture the lowest byte is the most significant byte while in Motorola architecture the highest byte of a word is the most significant one.

Q5. Get/Set and is statement related?

1. The terms get/set must be used where an attribute is accessed directly. employee.getName();

matrix.getElement (2, 4); employee.setName (name); matrix.setElement (2, 4, value);

2. is prefix should be used for boolean variables and methods.

isSet, isVisible, isFinished, isFound, isOpen

5) Aik long cyclomatic complexity se tha

Cyclomatic complexity

The concept of cyclomatic complexity is extremely useful in white box testing when analyzing the relative complexity of the program to be tested. Cyclomatic Complexity, V(G), for a flow graph G is defined as: V(G) = E - N + 2

6) aik short inspection conditions ka th

Inspection pre-conditions: A precise specification must be available before inspections. Team members must be familiar with the organization standards. In addition to it, syntactically correct code must be available to the inspectors. Inspectors should prepare a checklist that can help them during the inspection process.

7. Draw a diagram representing Three-Tier architecture of Virutal University Learning Management System (VULMS).
