Function overloading is when multiple functions have the same name but different parameters. Polymorphism is the ability of an object to take on many forms.

• Function overloading allows multiple functions with the same name but different parameters to be defined.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Function overloading is resolved at compile-time, while polymorp

• Use printf() function to print the name on the screen.

Code for arranging numbers in sorted order

• Use a sorting algorithm like bubble sort, insertion sort, or quicksort

• Determine if the numbers are integers or floating point numbers

• Consider the size of the input array and the time complexity of the algorithm

• Check for edge cases like empty array or array with only one element

Data mining is the process of discovering patterns and insights from large datasets.

• It involves using statistical and machine learning techniques to analyze data

• The goal is to extract useful information and knowledge from the data

Sorting is the process of arranging data in a particular order.

• Sorting is used to organize data for easier access and retrieval.

• There are various sorting algorithms such as bubble sort, insertion sort, quicksort, etc.

• Sorting can be done in ascending or descending order.

• Examples of sorting include sorting a list of names alphabetically or sorting a list of numbers in numerical order.

Heap sorting is a comparison-based sorting algorithm that divides the input into a sorted and an unsorted region, while insertion sorting builds the final sorted array one item at a time.

• Heap sorting has a worst-case time complexity of O(n log n), while insertion sorting has a worst-case time complexity of O(n^2)

• Heap sorting is not an in-place sorting algorithm, while insertion sorting is

• Heap sorting is more efficient ...read more

Type casting is the process of converting a variable from one data type to another.

• It is also known as type conversion.

• It can be done implicitly or explicitly.

• Explicit type casting involves the use of casting operators.

• Examples include converting an integer to a string or a float to an integer.

• Type casting can lead to loss of data or precision.

Inheritance is a mechanism in OOP where a new class is derived from an existing class.

• Single Inheritance: A derived class inherits from a single base class.

• Multiple Inheritance: A derived class inherits from multiple base classes.

• Multilevel Inheritance: A derived class is created from another derived class.

• Hierarchical Inheritance: Multiple derived classes inherit from a single base class.

• Hybrid Inheritance: Combinatio

The source code for doubly linked list is a data structure that contains nodes with pointers to the previous and next nodes.
