Q121

In the case of Decimal fixed point type in Ada language, the distance between values is implemented as a power of ______.

A) 10
B) 2
C) 8
D) 16

AI Explanation

In Ada, decimal fixed point types define the distance between values using a power of 10. This allows precise representation of decimal values for applications requiring fixed-point arithmetic.

Q122

Correct syntax of creating variable of a specific length in Ada is:

A) Some_String: String(1..20);
B) Some_String: String(1,20);
C) Some_String: String(1 : 20);
D) Some_String: String(1>20);

AI Explanation

Ada uses a range specification with two dots (..) to define the length of a string variable. This declaration creates a string with indexes from 1 to 20.

Q123

We use tagged type in Ada for ________________.

A) Abstraction
B) Polymorphism
C) Inheritance
D) Encapsulation

AI Explanation

Tagged types in Ada are primarily used to support inheritance and object-oriented programming. They allow new types to be derived from existing tagged types.

Q124

A/An _________________is a sequence of ordered enumeration literals in Ada.

A) Struct type
B) Float data type
C) String data type
D) Enumeration type

AI Explanation

In Ada, an enumeration type is a sequence of ordered enumeration literals. Each literal represents a distinct value in the defined type.

Q125

Which of the following statement of LISP generate an error?

A) >(+ (/ 3 5) 4)
B) >(+ (sqrt 4) 4.0)
C) >(sqrt x)
D) >(setq x 3.0)

AI Explanation

In LISP, the sqrt function requires a valid numeric argument. If x has not been assigned a numeric value, evaluating (sqrt x) will generate an error.

Q126

A ‘break’ statement in C-language is used to exit from loop structure. It’s alternative in Ada language is:

A) kill
B) breakif
C) exit
D) terminate

AI Explanation

In Ada, the exit statement is used to terminate a loop, similar to the break statement in C. It allows immediate transfer of control out of the loop.

Q127

Lists can be constructed (created and extended) with the help of ________ basic functions in LISP.

A) Five
B) Three
C) Two
D) Four

AI Explanation

In LISP, lists are constructed and extended using three basic functions: cons, list, and append. These functions provide fundamental list creation and manipulation capabilities.

Q128

All of the following were main design goals of Ada language EXCEPT:

A) Design language for the Department of Defence (USA)
B) Avoid unintentional mistakes during programming
C) Designing a portable language
D) Program reliability and maintenance

AI Explanation

Ada was developed for the US Department of Defense, but this was a motivation for its creation rather than a design goal of the language itself. Goals included reliability, portability, and reducing programming errors.

Q129

Using Ada, the correct way to declare a floating point type with 15 decimal digits of precision is __________.

A) type Double is digit 15;
B) type Double in digit 15;
C) type Double in digits 15;
D) type Double is digits 15;

AI Explanation

Ada floating point types are declared using the 'digits' keyword to specify the required decimal precision. The syntax 'type Double is digits 15;' defines a floating point type with 15 digits of precision.

Q130

In Ada, the correct values of the following modular type are _______________. type M is mod 7;

A) 1,2,3,4,5,6,7
B) 0,1,2,3,4,5,6
C) 1,2,3,4,5,6
D) 0,1,2,3,4,5

AI Explanation

In Ada, a modular type declared as 'mod 7' has values ranging from 0 to one less than the modulus value. Therefore, the valid values are 0 through 6.

Q131

Which of following is the membership operator in Ada?

A) @
B) ^
C) mem
D) in

AI Explanation

The 'in' operator is used as the membership operator in Ada. It checks whether a value belongs to a specified range or enumeration type.

Q132

In Ada, elementary types are also termed as ___________.

A) Built-in Types
B) Static Types
C) User-defined Types
D) Public Types

AI Explanation

In Ada, elementary types are also known as built-in types because they are predefined by the language. They include types such as integer, floating point, and Boolean.

A) Exception
B) Declare
C) Return
D) Begin

AI Explanation

The symbols used for logical true and false in LISP are:

A) Tr and Fr
B) Y and N
C) T and NIL
D) T and F

AI Explanation

In LISP, the symbol T represents logical true and NIL represents logical false. These are the standard Boolean values used in LISP.

Q135

__________ operations in Ada language must have one of its parameters of the tagged type.

A) Primitive
B) Generic
C) Concurrent
D) Concurrent

AI Explanation

In Ada, primitive operations associated with tagged types must have at least one parameter of the tagged type. These operations support object-oriented features such as inheritance and dispatching.

Q137

The list of parameters in Ada subprograms is separated by ___________.

A) Colon
B) Comma
C) Semicolon
D) Dot

AI Explanation

Q138

Which of the following function of LISP assigns value 5 to symbol y?

A) >(setq,5,y)
B) >(setq 5 y)
C) >(setq y 5)
D) >(setq,y,5)

AI Explanation

In LISP, the setq function is used to assign a value to a symbol. The correct syntax places the variable first and the value second, so y is assigned the value 5.

Q139

_________________ is not a discrete type in Ada.

A) Integer type
B) String Type
C) Character type
D) Modular type

AI Explanation

In Ada, discrete types include integer, enumeration, character, and modular types. String types are not discrete types because they represent sequences of characters.
