Virtual inheritance allows a derived class to inherit from a base class without creating duplicate base class subobjects.

• Virtual inheritance is used to resolve the Diamond Problem in C++ where a class inherits from two classes that have a common base class.

• It ensures that only one copy of the base class is inherited by the derived class.

A class for string operations can include methods for concatenation, substring extraction, length calculation, etc.

• Create a class with methods like concatenateStrings, extractSubstring, calculateLength, etc.

• Use string manipulation functions like substring, concat, length, etc. within the class methods.

• Ensure error handling for edge cases like empty strings or out-of-bounds indices.

• Example: class StringOperations { concatenateStrings(str1, str2) { return str1.concat(str2); } }

Copy constructor is used to create a new object as a copy of an existing object, while assignment operator is used to assign values from one object to another.

• Copy constructor is called when a new object is created from an existing object, while assignment operator is called when an existing object is assigned values from another object.

• Copy constructor creates a new object with its own memory space, while assignment operator assigns values to an existing object's memory spac...read more

Singleton design pattern ensures a class has only one instance and provides a global point of access to it.

• Ensures a class has only one instance

• Provides a global point of access to that instance

• Commonly used in scenarios where only one instance of a class is needed, such as database connections or logging

Logic building/thinking is the process of analyzing and solving problems using reasoning and critical thinking skills.

• It involves breaking down complex problems into smaller, more manageable parts

• Identifying patterns and relationships between different pieces of information

• Using deductive and inductive reasoning to draw conclusions

• Applying logical principles to solve problems in various fields such as computer programming, mathematics, and science

• Developing algorithms and log...read more

Copy constructor is a special type of constructor which creates a new object as a copy of an existing object.

• Copy constructor is used to initialize a new object as a copy of an existing object.

• It takes an object of the same class as a parameter.

• It is called automatically when a new object is created from an existing object.

• Example: class MyClass { public: MyClass(const MyClass& obj) { // copy constructor logic } };

GD&T symbols are used to specify tolerances in manufacturing processes such as sheet metal and casting.

• GD&T symbols are used to communicate design intent and specify tolerances for manufacturing processes.

• Sheet metal manufacturing involves cutting, bending, and forming sheet metal into various shapes and sizes.

• Casting involves pouring molten metal into a mold to create a specific shape.

• GD&T symbols commonly used in sheet metal manufacturing include flatness, perpendicularity,...read more

A static function is a function that is associated with a class rather than an instance of the class.

• Static functions can be called without creating an instance of the class.

• Static functions are commonly used for utility functions that do not require access to instance-specific data.

• Static functions are declared using the 'static' keyword in many programming languages.

• Example: 'Math.max()' in JavaScript is a static function.

Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

• Start with 0 and 1 as the first two numbers in the series

• Add the previous two numbers to get the next number in the series

• Repeat this process to generate the Fibonacci series

Solid design involves creating 3D models with volume, while sheetmetal design focuses on creating 2D models that can be bent or formed into 3D shapes.

• Solid design is used for creating objects with volume and complex shapes.

• Sheetmetal design is used for creating objects that can be easily bent or formed, typically used in manufacturing processes like metal fabrication.

• Solid design often involves features like fillets, chamfers, and complex geometries.

• Sheetmetal design focuses ...read more

Python is a high-level, interpreted programming language with dynamic semantics.

• Python has several built-in data types including integers, floats, strings, booleans, and complex numbers.

• It also has built-in data structures like lists, tuples, and dictionaries.

• Python supports object-oriented programming and has a rich standard library.

• Examples: x = 5 (integer), y = 3.14 (float), z = 'hello' (string), a = True (boolean), b = 2 + 3j (complex number), c = [1, 2, 3] (list), d = (4...read more

Header files in C programming are used to declare functions, variables, and macros that can be used in multiple source files.

• Header files typically have a .h extension and contain function prototypes, type definitions, and global variables.

• They are included in source files using the #include directive.

• Example: #include includes the standard input/output functions in the program.

Geometric Dimensioning and Tolerancing (GD&T) symbols are used to define the geometry of parts and assemblies in engineering drawings.

• GD&T symbols include position, concentricity, symmetry, perpendicularity, parallelism, flatness, circularity, cylindricity, profile of a line, profile of a surface, etc.

• Each symbol has a specific meaning and is used to communicate the required tolerances for manufacturing and inspection processes.

• For example, the position symbol indicates the a...read more

Sheetmetal operation involves cutting, bending, and forming sheet metal to create various components.
