Q3
Which of the following is a distinct syntactic block?
  • A. Subroutines
  • B. Function
  • C. DefinitionCorrect
  • D. Modules
Explanation. Definitions bind values to names and act as distinct syntactic blocks rather than expressions.
Q4
The variables in a function definition are called as
  • A. Subroutines
  • B. Function
  • C. Definition
  • D. ParametersCorrect
Explanation. In programming, the variables declared within a function definition are referred to as parameters.

  • C. Dynamic Functions
  • D. Pure functionsCorrect
Explanation. Pure functions are deterministic and always return the same output when given the same arguments.
Q10
The functions which cause side effects to the arguments passed are called
  • A. impure functionCorrect
  • B. Partial Functions
  • C. Dynamic Functions
  • D. Pure functions
Explanation. Impure functions can modify external variables, causing side effects during their execution.
