  • Ans. 

    Go supports object-oriented programming principles through struct types and methods.

    • Go uses struct types to define objects with fields and methods.

    • Methods can be defined on struct types to provide behavior to objects.

    • Go does not have classes like traditional OOP languages, but it supports encapsulation, inheritance, and polymorphism through struct embedding and interfaces.

  • Q2. Internal working of arrays and slices
  • Ans. 

    Arrays are fixed-size collections of elements of the same type, while slices are dynamic arrays with a flexible size.

    • Arrays have a fixed size determined at compile time.

    • Slices are dynamic arrays that can grow or shrink.

    • Arrays and slices are both zero-indexed.

    • Arrays are passed by value, while slices are passed by reference.

    • Example: var arr [3]string = [3]string{"apple", "banana", "orange"}

    • Example: var slice []string = [
