Virtual functions allow polymorphism in C++. Vtable is a lookup table for virtual functions and vpointer points to it.

• Virtual functions are used to achieve runtime polymorphism

• Vtable is a table of function pointers for virtual functions

• Vpointer points to the vtable of the object

• When a virtual function is called, the vpointer is used to lookup the correct function in the vtable

• Vtable is created at compile time and is unique for each class

Yes, we can handle exceptions in constructor and destructor.

• In constructor, we can use try-catch block to handle exceptions.

• In destructor, we should avoid throwing exceptions as it can lead to undefined behavior.

• If an exception is thrown in constructor, the object is not fully constructed and should be destroyed.

• If an exception is thrown in destructor, it should be caught and handled properly to avoid program termination.

Pure virtual functions are functions with no implementation in base class. Pure virtual destructor is used to ensure proper destruction of derived objects.

• Pure virtual functions are declared with the syntax virtual void functionName() = 0;

• Classes with pure virtual functions are called abstract classes and cannot be instantiated.

• Derived classes must implement pure virtual functions to be instantiated.

• Pure virtual destructors are used to ensure proper destruction of derived obj...read more

• GL coding involves assigning codes to transactions for easy tracking and analysis

• P2P cycle includes steps like requisition, purchase order, receipt of goods, and payment

• Journal entries are used to record financial transactions in the general ledger

Option chain is a list of all available options for a particular stock. Open interest is the total number of outstanding contracts.

• Option chain provides information about the strike price, expiration date, and premium of each option.

• Open interest indicates the number of contracts that have not been settled or closed.

• High open interest suggests high liquidity and active trading in that particular option.

• Open interest is used to analyze market trends and predict future price mo...read more

A strike in futures is a predetermined price at which a buyer and seller agree to trade an underlying asset in the future.

• A strike price is set when a futures contract is created

• It is the price at which the underlying asset will be bought or sold in the future

• If the market price of the asset is above the strike price, the buyer profits and vice versa

• For example, if a futures contract for gold has a strike price of $1,500 and the market price of gold rises to $1,600, the buyer...read more
