Create a DbContext class that inherits from DbContext and represents the database.
Use dependency injection to inject the DbContext into the API controllers.
Dependency Injection is a design pattern where the dependencies of an object are provided externally rather than created within the object itself.
Dependencies are injected into a class through constructor injection, setter injection, or interface injection.
This helps in achieving loose coupling between classes and makes the code more testable and maintainable.
Example: Instead of creating an instance of a dependency wit...

Start by checking if the number is less than 2, in which case it is not prime.
Iterate from 2 to the square root of the number and check if any of them divide the number evenly.
If a divisor is found, the number is not prime. Otherwise, it is prime.

Abstraction: Hiding the complex implementation details and showing only ...
Structures in C are user-defined data types that allow grouping of variables of different data types under a single name.
Structures are used to represent a record which consists of different data types.
They are defined using the 'struct' keyword.
Each variable in a structure is called a member.
Structures can be nested within other structures.
Example: struct employee { int emp_id; char emp_name[50]; float emp_salary; };
