There are two ways to throw an exception in exception handling.
Exceptions can be thrown using the throw keyword.
Exceptions can also be thrown implicitly by the runtime system.
Examples of explicit throwing include throw new Exception() and throw new IOException().
Examples of implicit throwing include division by zero or null pointer dereference.
Reverse a given string using array of characters.
Create an empty array to store the reversed string.
Loop through the original string from end to start.
Push each character into the empty array.
Join the array to form the reversed string.
Copy constructor creates a new object by copying an existing object, while assignment operator assigns the value of an existing object to another object.
Copy constructor is used to initialize a new object with the values of an existing object.
Assignment operator is used to assign the value of an existing object to another object.
Copy constructor is called when a new object is created from an existing object.
Assignment ...
A copy constructor is used to create a new object with the same values as an existing object. We implement our own to ensure proper copying of data members.
A copy constructor is needed when we want to create a new object with the same values as an existing object.
If we don't implement our own copy constructor, the default copy constructor provided by the compiler may not copy data members properly.
We can implement our ...
QT framework is used for developing cross-platform applications with a single codebase.
QT provides a wide range of libraries and tools for developing GUI applications.
QT supports multiple platforms including Windows, Linux, macOS, Android, and iOS.
QT has a large community and extensive documentation.
QT is written in C++ and supports other programming languages like Python and Java.
QT is used by companies like Autodesk,...
RTTI stands for Run-Time Type Identification.
RTTI is a feature in C++ that allows the type of an object to be determined at runtime.
It is used to implement dynamic_cast, typeid, and exception handling.
RTTI can be used to check if an object is of a certain type before casting it.
It can also be used to determine the type of an object in order to perform specific operations on it.
I have used the Singleton and Factory design patterns in my previous projects.
Singleton pattern was used to ensure only one instance of a class is created and provide a global point of access to it.
Factory pattern was used to create objects without exposing the instantiation logic to the client and provide a way to create objects of a family without specifying their concrete classes.
QT supports multiple operating systems and cross-compilation is possible.
QT supports Windows, macOS, Linux, Android, iOS, and many other operating systems.
Cross-compilation is possible, meaning you can compile for different operating systems on a single machine.
QT also supports embedded systems like Raspberry Pi and BeagleBone.
QT provides pre-built binaries for some operating systems, but for others, you may need to co...
QPointer is a deprecated Qt class used for storing and managing pointers.
QPointer is used to avoid dangling pointers in Qt applications.
It is a template class that can be used with any QObject-derived class.
QPointer is now deprecated and replaced by QWeakPointer.
QPointer can be used to check if a QObject is still valid before accessing it.
dpointer is a Qt framework concept used for efficient memory management.
dpointer is a private implementation pointer.
It is used to hide implementation details from the public API.
dpointer allows for copy-on-write semantics.
It reduces memory usage and improves performance.
Example: QString uses dpointer to store its data.
Example: QSharedDataPointer is used to share data between objects.
I have used Qt version 5.12.3 for my previous project.
Qt version 5.12.3 was used in my previous project
I have experience working with Qt 5.15.2 as well
I am familiar with the features and functionalities of Qt 5.12.3
To check if a linked list is circular, use two pointers, one moving at twice the speed of the other. If they meet, the list is circular.
Use two pointers, one moving at twice the speed of the other
If the faster pointer catches up to the slower pointer, the list is circular
If the faster pointer reaches the end of the list, the list is not circular
Find the merge point of 2 linked lists.
Traverse both lists and find their lengths
Move the pointer of the longer list to the same distance as the shorter list
Move both pointers until they meet at the merge point
If there is no merge point, return null
To find a string in a sorted array of strings.
Use binary search algorithm to search for the string in the array.
Compare the search string with the middle element of the array.
If the search string is less than the middle element, search in the left half of the array.
If the search string is greater than the middle element, search in the right half of the array.
Repeat the process until the string is found or the search sp
Singleton class is a design pattern that restricts the instantiation of a class to one object.
To create a singleton, we need to make the constructor private and provide a static method to get the instance of the class.
To delete the singleton object, we can simply set the instance to null.
Singletons are useful when we need to ensure that only one instance of a class exists throughout the application.
Example: Logger clas...
Dynamic memory allocation in C/C++ is done using malloc(), calloc(), realloc() functions. C++ also has new and delete operators.
malloc() allocates memory block of specified size
calloc() allocates memory block and initializes it to zero
realloc() changes the size of previously allocated memory block
new operator in C++ allocates memory and calls constructor
delete operator in C++ deallocates memory and calls destructor
