Q101

Which of the following is used to represent code and data in LISP?

A) T-symbol
B) S-expression
C) Package
D) >cdr statement

AI Explanation

LISP uses S-expressions (symbolic expressions) to represent both code and data. This uniform representation is a fundamental feature of LISP.

Q102

Each ‘if’ statement in Ada language must be terminated with corresponding:

A) ‘then’ statement
B) ‘end if’ statement
C) ‘else’ statement
D) ‘elsif’ statement

AI Explanation

Every if statement in Ada must be terminated with the 'end if;' statement. This clearly marks the end of the conditional block.

Q103

Data types in Ada can be extended through:

A) Inheritance
B) Functions
C) Arrays
D) Polymorphism

AI Explanation

Ada supports extending data types through inheritance, especially using tagged types. This allows new types to be derived from existing ones with additional features.

Q104

A 'while' loop in Ada is terminated by ______ keyword.

A) break
B) end loop
C) end while
D) exit

AI Explanation

In Ada, while loops are terminated using the 'end loop;' keyword. Ada uses this syntax for all loop constructs, including while and for loops.

Q105

The return value of a function in a tagged type of Ada language can be an instance of:

A) Another function
B) Package
C) Tagged type
D) Template

AI Explanation

In Ada, a function associated with a tagged type can return an instance of that tagged type. This supports object-oriented programming features such as type extension and polymorphism.

Q106

Using Ada language, the correct way to declare an integer type with the lower value being 1 and the upper value being 100 is __________.

A) type Marks is range 1;;100;
B) type Marks is range 1..100;
C) type Marks is range 1::100;
D) type Marks is range 1,,100;

AI Explanation

Ada uses the range syntax with two periods (..) to specify lower and upper bounds of an integer type. The declaration creates an integer type named Marks with values from 1 to 100.

Q107

__________ function is used to forbid the evaluation of x in LISP.

A) (setq x)
B) (cons x)
C) (quote x)
D) (setf x)

AI Explanation

In LISP, the quote function prevents evaluation of an expression and returns it as a literal value. Therefore, (quote x) keeps x from being evaluated.

Q108

If you want to assign a value 10 to a variable named ‘Roll_No’ in Ada language, then which of the following is a correct way to do that?

A) Roll_No -> 10;
B) Roll_No : 10;
C) Roll_No = 10;
D) Roll_No := 10;

AI Explanation

Ada uses the assignment operator ':=' to assign values to variables. The statement Roll_No := 10; correctly assigns the value 10 to Roll_No.

Q109

Which of the following is a valid symbol in LISP?

A) Roll No.
B) CGPA
C) ‘Price’
D) “Employee ID”

AI Explanation

In LISP, symbols can contain letters and represent identifiers. CGPA is a valid symbol, while names containing spaces or quotation marks are not valid symbols in this context.

Q110

Which of the following is the Range Operator in ADA programming language?

A) ,,
B) %
C) ..
D) #

AI Explanation

In Ada, the double dot (..) symbol is the range operator used to specify ranges of values. It is commonly used in type declarations, array bounds, and loop ranges.

Q111

Generics in Ada language are like ________ in C++.

A) templates
B) functions
C) classes
D) enumerators

AI Explanation

Ada generics are similar to templates in C++ because both allow the creation of reusable code that can work with different data types. They support parameterized programming.

Q112

Ada language supports encapsulation through:

A) Packages
B) Functions
C) Streams
D) Structures

AI Explanation

Ada supports encapsulation through packages, which combine related data types, variables, and subprograms while controlling visibility. Packages help organize and protect program components.

CS508 Final Term AI Solved

Q113

The structure that is used to group data and subprograms in Ada language is called:

A) Array
B) Package
C) Class
D) Function

AI Explanation

In Ada, packages are structures used to group related data and subprograms together. They provide modularity and encapsulation for software design.

Q114

In which of the following style of programming, evaluation of expression is emphasized rather than execution of commands?

A) Functional Programming
B) Aspect-based Programming
C) Generic Programming
D) Object-oriented Programming

AI Explanation

Functional programming emphasizes the evaluation of expressions rather than the execution of commands. It focuses on functions and immutable data concepts.

Q115

In Ada, Boolean is a _______________ enumeration type.

A) Pre-defined
B) User defined
C) Client-defined
D) Post-defined

AI Explanation

In Ada, Boolean is a pre-defined enumeration type with two values: True and False. It is built into the language and does not need to be declared by the programmer.

Q116

In Ada programming language, _____________ operator is used to access individual fields of a record type.

A) Colon
B) Space
C) Dot
D) Exclamation

AI Explanation

Ada uses the dot (.) operator to access individual fields of a record type. It separates the record object name from the specific field name.

Q117

A function in Ada language can have:

A) any number of ‘return’ statements
B) only one ‘return’ statement
C) at-least three ‘return’ statements
D) maximum two ‘return’ statements

AI Explanation

An Ada function can contain multiple return statements, although only one is executed during a particular call. Each return statement provides the function's result and exits the function.

Q118

Which of the following operator in Ada is used to check the non-equality of two operands?

A) !=
B) /=
C) ==!
D) <>

AI Explanation

In Ada, the '/=' operator is used to test whether two operands are not equal. It is the equivalent of the not-equal operator in many other programming languages.

A) to help testers to test Ada application easily
B) to make it difficult for developers to make mistakes
C) to help developers to code the software in lesser time
D) to help develop an automated IDE for Ada

AI Explanation

A major design goal of Ada was to improve software reliability and safety by reducing programming errors. Strong typing and strict language rules help developers avoid mistakes.
