  • Q1. What are functional relations in the context of database management systems (DBMS)?
  • Ans. 

    Functional relations in DBMS define a relationship between input and output values where each input has a unique output.

    • Functional relations ensure that each input value maps to only one output value.

    • They are commonly used in database design to enforce data integrity and consistency.

    • For example, in a table storing employee information, the employee ID can be a functional key that uniquely identifies each employee.

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

  • Q1. Use of namespace in c++
  • Ans. 

    Namespace in C++ is used to avoid naming conflicts and organize code.

    • Namespace allows grouping of related functions, classes, and variables.

    • It helps in avoiding naming conflicts by providing a unique identifier to each entity.

    • Namespace can be nested within another namespace.

    • Using namespace keyword, we can access the entities within a namespace.

  • Q2. How would++(++i) work
  • Ans. 

    The expression would increment the value of i twice before using it in the operation.

    • The value of i would be incremented by 2 before being used in the operation.

    • This is equivalent to writing i = i + 2; followed by the operation using the new value of i.

    • For example, if i was initially 3, the expression would evaluate to 6.
