SQL joins are used to combine rows from two or more tables based on a related column between them.
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.
INNER JOIN returns rows when there is at least one match in both tables.
LEFT JOIN returns all rows from the left table and the matched rows from the right table.
RIGHT JOIN returns all rows from the right table and the matched rows from the left table.

Modal analysis is a technique used to study the dynamic characteristics of a system by identifying its modes of vibration.
Modal analysis is used to determine the natural frequencies, damping ratios, and mode shapes of a structure or component.
It helps in understanding the behavior of a system under different loading conditions.
Modal analysis is commonly used in engineering fields such as aerospace, civil, and mechanica...
DOF stands for Degrees of Freedom and refers to the number of independent variables in an element.
1D elements have 2 DOF, typically displacement in x and rotation about x
2D elements have 3 DOF, typically displacement in x and y, and rotation about z
3D elements have 6 DOF, typically displacement in x, y, and z, and rotation about x, y, and z
Mesh quality criteria are used to evaluate the accuracy and reliability of a mesh in numerical simulations.
Mesh quality criteria assess the shape, size, and connectivity of mesh elements.
Common criteria include aspect ratio, skewness, and orthogonality.
Aspect ratio measures the elongation of elements, with lower values indicating better quality.
Skewness measures the distortion of elements, with values close to zero ind...

Copy constructor creates a new object by copying the values of an existing object.
Copy constructor is used to create a new object with the same values as an existing object.
It is invoked when a new object is initialized with an existing object.
It is used to avoid shallow copy and ensure deep copy of objects.
Example: MyClass obj1; MyClass obj2 = obj1; //copy constructor called to create obj2
Shallow copy creates a new object with the same reference as the original, while deep copy creates a new object with a new reference.
Shallow copy only copies the reference to the original object, so changes made to the copy will affect the original object.
Deep copy creates a new object with a new reference, so changes made to the copy will not affect the original object.
In Python, shallow copy can be made using the cop...
Vectors are dynamic arrays that allocate memory dynamically. They work by storing elements in contiguous memory locations.
Vectors allocate memory dynamically and store elements in contiguous memory locations
They can be resized dynamically as needed
Accessing elements is done using an index, similar to arrays
Inserting or deleting elements in the middle of a vector can be expensive as it requires shifting all subsequent e...
STL provides various containers like vector, list, map, set, etc.
Vector: Dynamic array with contiguous memory allocation
List: Doubly linked list
Map: Associative container with key-value pairs
Set: Associative container with unique keys
Deque: Double-ended queue
Stack: LIFO data structure
Queue: FIFO data structure
Ordered map maintains the order of insertion while unordered map does not.
Ordered map is implemented using a balanced binary search tree while unordered map is implemented using a hash table.
Ordered map is useful when we need to maintain the order of insertion while unordered map is useful when we need faster access to elements.
Example of ordered map: std::map in C++, Example of unordered map: std::unordered_map in C++
Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as if they were the same type.
Polymorphism is achieved through method overriding and method overloading.
Method overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class.
Method overloading is when a class has two or more methods with the same...
Name mangling is used by compilers to differentiate between different functions with the same signature.
Name mangling is a process of encoding/decoding function names to include additional information such as parameter types and namespaces.
This allows the compiler to differentiate between functions with the same name and signature.
For example, in C++, two functions with the same name and signature but in different name...

Virtual functions allow dynamic binding of functions at runtime. Vptr and Vtable are used to implement this feature.
Virtual functions are declared in base class and can be overridden in derived classes.
Vptr is a pointer to Vtable which contains addresses of virtual functions.
Virtual function is needed to achieve polymorphism and to allow derived classes to have their own implementation of a function.
Virtual functions a...

Check if a point is inside or outside a circle
Calculate the distance between the center of the circle and the given point using the distance formula
If the distance is less than the radius of the circle, the point is inside the circle
If the distance is equal to the radius of the circle, the point is on the circle
If the distance is greater than the radius of the circle, the point is outside the circle
Smart pointers are objects that manage the memory of dynamically allocated objects, preventing memory leaks and dangling pointers.
Smart pointers are a type of RAII (Resource Acquisition Is Initialization) technique.
They automatically delete the object they point to when it is no longer needed.
Examples of smart pointers include unique_ptr, shared_ptr, and weak_ptr in C++.
They are used to prevent memory leaks and danglin...
