The Need for Operator Overloading
Let’s revisit the clockType class from Chapter 11. Consider the following code snippet:
clockType noon(12, 0, 0);clockType classTime(11, 30, 0);noon.printTime();classTime.incrementSeconds();if (noon.equalTime(classTime)) { cout << "The times are equal" << endl;}These statements work as intended,

First, clean and adjust the spark plugs. Clean the high-tension wires, distributor cap, and coil. Check the spark plugs while the engine is running. Connect a voltmeter to the positive terminal of the coil; it should show the same voltage as the battery. Verify that impulses are reaching the module by connecting an AC voltmeter. Check the pulse generated by the coil with an ohmmeter connected at both ends; it should indicate a resistance value. Test continuity.

Ques: 1 How to eliminate duplicate rows in a table?
Ans:
Use a primary key if the column is like ID or number. Alternatively, you can apply a unique constraint on the column.
Ans:
Deletion of duplicate records:
delete from emp a where a.rowid > (select min(b.rowid) from emp b where a.rowid=b.rowid)
or
delete from table t1 where t1.rowid
Ques: 2 What is the use of the ‘in’ command?
Ans:
Suppose you want to choose a specific department, then you can use the ‘in’ command.
Example:
select ename,sal from emp

1. Computer Model Questions
What question does a computer model answer? What specific question does your model answer for its users? (Pg. 71 Let’s Go)
“Remember, models answer the question ‘What if…?’. Your model will answer the question ‘What if a person were doing things that cause global warming and how could they change their behavior?’ for lots of different people.”

What is a Structure?
A structure is something that supports an object or a load.
Requirements of a Structure
A structure must:
- Be strong enough to support its own weight and any load that is put on it.
- Be stable (not topple over easily when a force acts on it).
- Resist deformation without losing its shape more than expected.
Types of Structures
There are three types of structures:
- Mass Structures: Solid structures that rely on their own weight to resist loads. Examples include Roman bridges, aqueducts, walls,
