A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function with the same signature in a derived class.
Virtual functions allow for dynamic polymorphism in object-oriented programming.
They are used to achieve runtime polymorphism by allowing a function to be called based on the type of object it is called on.
Virtual functions are declared in a base cl...
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or classes.
Examples include method overloading and method overriding in object-oriented programming.
Structure is a collection of variables of different data types while union is a collection of variables of same data type.
Structure allocates memory for all its variables while union allocates memory for only one variable at a time.
Structure is used when we want to store different types of data while union is used when we want to store only one type of data.
Structure is accessed using dot operator while union is access...
Dangling pointers can be avoided by setting them to NULL after freeing the memory they point to.
Always initialize pointers to NULL.
Set pointers to NULL after freeing the memory they point to.
Avoid accessing memory through a pointer after it has been freed.
Use smart pointers or garbage collection to automate memory management.
A program to print Fibonacci series using recursion.
Define a recursive function that takes an integer n as input
Base case: if n is 0 or 1, return n
Recursive case: return the sum of the previous two Fibonacci numbers
Call the recursive function with the desired number of terms and print the result
It had quants,verbal and logical qns
Embedded C is a subset of the C programming language, specifically designed for programming embedded systems.
Embedded C is optimized for resource-constrained systems with limited memory and processing power.
It includes additional keywords and features for controlling hardware directly.
Embedded C often involves working with microcontrollers, sensors, and other hardware components.
Regular C can be used for general-purpos

A Watchdog timer is a hardware or software mechanism that automatically resets or restarts a device if it stops responding or functioning properly.
Watchdog timer is used to prevent system crashes or freezes by monitoring the system and resetting it if necessary.
It is commonly used in embedded systems, where reliability is crucial.
The timer needs to be periodically reset by the software to prevent the system from resett...
