Quiz on Basic Semantics in Programming Languages

What is the fundamental abstraction mechanism in programming languages?

• Use of functions

• Use of data types

• Use of names or identifiers

• Use of loops

What does the term 'binding' refer to in programming languages?

• The association of attributes with names

• The declaration of variables

• The process of executing code

• The allocation of memory

Which of the following is an example of static binding?

• Dynamic memory allocation

• Using a pointer

• Declaring a constant

• Assigning a value to a variable during execution

What is a symbol table?

• A method for parsing code

• A list of all variables in a program

• A function that expresses the binding of attributes to names

• A data structure for managing memory

In block-structured languages, what is the scope of a binding?

• The global scope

• Only the function where it is declared

• The block in which the declaration appears

• The entire program

What is the difference between static and dynamic attributes?

• There is no difference

• Static attributes are only for constants, dynamic attributes are for variables

• Static attributes are bound prior to execution, dynamic attributes during execution

• Static attributes are bound during execution, dynamic attributes are not

What does the term 'dangling reference' refer to?

• A reference that is not defined

• A reference to a global variable

• A reference to a variable that has been deallocated

• A reference to a variable that is still in scope

Which of the following is an example of a compile-time constant?

• A variable assigned during execution

• A constant defined using a literal

• A pointer variable

• A dynamically allocated memory

What is the purpose of the environment in programming languages?

• To parse the syntax of the program

• To optimize memory usage

• To manage the execution of code

• To maintain bindings of names to locations

What is 'overload resolution'?

• The process of determining which overloaded function to call

• The process of allocating memory for functions

• The process of defining new functions

• The process of removing unused functions
