SQL is a programming language used to manage and manipulate relational databases.

• SQL stands for Structured Query Language

• It is used to create, modify, and query databases

• Common commands include SELECT, INSERT, UPDATE, and DELETE

• Examples of database management systems that use SQL include MySQL, Oracle, and Microsoft SQL Server

Schema is a blueprint or structure that defines the organization of data in a database.

• Schema is used to define the structure of a database.

• It includes information about tables, columns, data types, relationships, and constraints.

• It helps ensure data consistency and integrity.

• Examples of schema include SQL Server, Oracle, and MySQL.

• Schema can also refer to the organization of data in XML or JSON documents.

Exception handling is a mechanism to handle runtime errors in Java programs.

• Exceptions are objects that represent errors or exceptional conditions that occur during program execution.

• Java provides try-catch-finally blocks to handle exceptions.

• The try block contains the code that might throw an exception.

• The catch block catches the exception and handles it.

• The finally block contains code that is executed regardless of w...read more

Yes, a schema can consist of multiple databases.

• A schema is a logical container for database objects.

• Multiple databases can be grouped under a single schema.

• For example, a company may have separate databases for HR, finance, and sales, but all under the same schema.

• This allows for easier management and organization of the databases.

Program to display prime numbers from 1-35

• Loop through numbers 1-35

• Check if each number is prime

• If prime, display the number

A program to reverse a string

• Create an empty string to store the reversed string

• Loop through the original string from the end to the beginning

• Add each character to the new string

• Return the new string

Polymorphism is the ability of an object to take on many forms.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It can be achieved through method overloading or method overriding.

• Example: A shape class can have different subclasses like circle, square, triangle, etc. and all can be treated as shapes.

• Polymorphism helps in achieving code reusability and flexibility.

Yes, method overloading is possible in C++.

• Method overloading allows multiple functions with the same name but different parameters.

• The compiler determines which function to call based on the number and types of arguments passed.

• Example: void print(int x), void print(float x), void print(char x) can all be overloaded.

• Overloading can also be done with operators like +, -, *, /, etc.

• Overloading improves code readability

I will use software tools that are relevant to my BE project.

• The software tools I will use will depend on the nature of my BE project.

• For example, if my project involves designing a circuit, I may use software like LTSpice or Proteus.

• If my project involves programming, I may use software like Visual Studio or Eclipse.

• I will also use software for data analysis and visualization, such as MATLAB or Python.

• Ultimately, I wi...read more

Yes, we can write int func() and int func(int a) in a single class.

• We can overload the function with different parameters.

• The function with no parameter is called default constructor.

• Example: class MyClass { int func(); int func(int a); };

• Both functions can have different implementations.
