C is a procedural programming language, while C++ is an object-oriented language that extends C with classes and objects.

• C is a procedural language; C++ supports both procedural and object-oriented programming.

• C uses functions as the primary building blocks; C++ uses classes and objects.

• C does not support function overloading; C++ allows function overloading.

• C has no built-in support for encapsulation; C++ provides enc...read more

A class is a blueprint for creating objects in programming, encapsulating data and behavior.

• Defines properties (attributes) and methods (functions) for objects.

• Example: A 'Car' class may have attributes like 'color' and 'model', and methods like 'drive()' and 'stop()'.

• Supports inheritance, allowing new classes to derive from existing ones.

• Example: A 'ElectricCar' class can inherit from 'Car' and add features like 'char...read more

An object is a distinct entity that encapsulates data and behavior in programming, representing real-world or abstract concepts.

• Objects are instances of classes in object-oriented programming.

• They can contain attributes (data) and methods (functions).

• Example: A 'Car' object may have attributes like 'color' and 'model', and methods like 'drive()' and 'stop()'.

• Objects promote code reusability and modularity.

A static variable retains its value between function calls and is shared across all instances of a class in programming.

• Static variables are initialized only once and exist for the lifetime of the program.

• In C/C++, a static variable inside a function retains its value between calls.

• In Java, static variables belong to the class rather than any instance.

• Example in C: static int count = 0; - count retains its value across...read more

Static variables are limited to their function scope, while global variables are accessible throughout the entire program.

• Static variables retain their value between function calls, e.g., 'static int count = 0;' in a function.

• Global variables are declared outside any function and can be accessed from any function, e.g., 'int globalCount = 0;'

• Static variables are not visible outside their defining function, while global...read more

Pointers are variables that store memory addresses of other variables, enabling efficient data manipulation in programming.

• Pointers allow direct memory access, which can enhance performance in applications.

• Example: In C, 'int *ptr;' declares a pointer to an integer.

• Pointers can be used to dynamically allocate memory using functions like 'malloc()' in C.

• They enable the creation of complex data structures like linked lis...read more

Structures are organized systems or frameworks that define the arrangement and relationships of components within a system.

• Structures can be physical, like buildings or bridges.

• In programming, structures refer to data types that group related variables.

• In biology, structures include the arrangement of cells in tissues.

• In organizations, structures define roles, responsibilities, and hierarchies.

A stack is a linear data structure that follows the Last In First Out (LIFO) principle for managing data.

• 1. Definition: A stack is a collection of elements with two main operations: push (add) and pop (remove).

• 2. LIFO Principle: The last element added to the stack is the first one to be removed.

• 3. Operations: Common operations include push, pop, peek (view top element), and isEmpty (check if stack is empty).

• 4. Example:...read more

Three steps for using functions in C.

• Declare the function with its return type, name, and parameters.

• Define the function by writing the code for it.

• Call the function by using its name and passing arguments if necessary.

The limit for the number of arguments passed to functions is not fixed. Arrays or structures can be used to pass more parameters.

• The limit for the number of arguments passed to functions is not fixed and depends on the programming language and system architecture.

• In C programming language, there is no limit on the number of arguments that can be passed to a function.

• In Java, the maximum number of arguments that can be ...read more

A union is an organized group of workers that collectively bargain for better wages, benefits, and working conditions.

• Unions advocate for workers' rights and negotiate labor contracts.

• Examples include the United Auto Workers (UAW) and the American Federation of Teachers (AFT).

• Unions can provide legal representation and support during disputes with employers.

• They often engage in political lobbying to influence labor law...read more

if else is used for simple conditions while switch case is used for multiple conditions.

• if else is a sequential decision-making statement while switch case is a multi-branch decision-making statement

• if else is used when there are only a few conditions to be checked while switch case is used when there are multiple conditions to be checked

• if else can have multiple conditions in a single statement while switch case can o...read more

Member functions are functions that are defined inside a class and can access the class's private and protected members.

• Member functions are also known as methods.

• They can be used to manipulate the data members of an object.

• They can be overloaded, meaning multiple functions with the same name but different parameters can exist within a class.

• They can be declared as const, meaning they do not modify the object's state.

• E...read more

Find the output of c=++a+b-- where a=5 and b=4.

• The value of a is incremented by 1 before the addition operation

• The value of b is decremented by 1 after the addition operation

• The final value of c is 10

• The value of a becomes 6 and the value of b becomes 3

10 plants can be planted in 5 rows with 4 plants in each row.

• Divide the plants into groups of 4.

• Arrange the groups in 5 rows.

• Each row will have 4 plants.

In Java, exceptions are handled using try-catch blocks, allowing for graceful error management and program stability.

• Use try-catch blocks to catch exceptions: try { // code that may throw an exception } catch (ExceptionType e) { // handle exception }

• Finally block can be used for cleanup: try { // code } catch (Exception e) { // handle exception } finally { // cleanup code }

• Throwing exceptions: Use...read more
