Q62

what will be the resulting value of y in the following SNOBOL statement y = 2 ** 3.

A) 8
B) 5
C) 9
D) 6

AI Explanation

In SNOBOL, the exponentiation operator (**) calculates powers. Therefore, 2 ** 3 evaluates to 8.

Q63

In FORTRAN _____ independent compilation was not supported.

A) I
B) 77
C) IV
D) 90

AI Explanation

FORTRAN I did not support independent compilation because it was designed with early compiler limitations. Later versions introduced more advanced compilation features.

Q64

Binary operator in SONOBOL must has at least ________ space(s) on both sides.

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

AI Explanation

A binary operator in SNOBOL must have at least one space on both sides to separate it from surrounding operands. This spacing rule helps the interpreter recognize the operator correctly.

Q65

What would be the output of following SNOBOL4 code? P = ('A' | 'B' | 'C' | 'D') $ V 'ZAIN' P OUTPUT = V

A) I
B) N
C) A
D) Z

AI Explanation

The SNOBOL pattern assigns the matched character from P to variable V. Since the pattern is matched against 'ZAIN', the first character selected is Z, which is then output.

Q66

The major issue with _______________ was that the developers had no or limited experience in software development.

A) C++
B) C#
C) SNOBOL
D) Java

AI Explanation

SNOBOL was developed by researchers who had limited experience in software development at the time. This lack of prior software engineering experience influenced some of the language's design characteristics.

Q67

Using SNOBOL, the correct way to create a one-dimensional array of 7 elements with the lower index being 2 and the upper index being 8.

A) X = ARRAY(‘2;8’)
B) X = ARRAY(‘2.8’)
C) X = ARRAY(‘2:8’)
D) X = ARRAY(‘2,8’)

AI Explanation

In SNOBOL, the ARRAY function uses a colon to specify the lower and upper bounds of a one-dimensional array. ARRAY('2:8') creates an array with indexes from 2 through 8.

The ability to create dynamic HTML documents was the primary objective of:

A) Ada
B) Java
C) SNOBOL
D) JavaScript

AI Explanation

JavaScript was created with the objective of enabling dynamic and interactive HTML documents. It became a core technology for client-side web development.

Q69

In SNOBOL, ______ acts as operator for string concatenation

A) Space
B) _
C) *
D)

AI Explanation

In SNOBOL, a space acts as the operator for string concatenation. It joins strings or patterns together to form a combined sequence.

Q70

Using SNOBOL, the correct way to create a dynamic array (i.e. takes its size at run time from user) is;

A) V = Array (Dynamic)
B) V = Array (Input)
C) V = Array (Runtime)
D) V = Array (Output)

AI Explanation

In SNOBOL, dynamic arrays can be created by obtaining their size during program execution. The Input option allows the array size to be determined from user input at runtime.

Q71

The first high level language was____________

A) Ada
B) Plankalkül
C) FORTRAN
D) SNOBOL

AI Explanation

Plankalkül, developed by Konrad Zuse in the 1940s, is considered the first high-level programming language. It introduced many concepts that influenced later language development.

Q72

Binary operator in SONOBOL must has at least ________ space(s) on both sides.

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

AI Explanation

In SNOBOL, binary operators require at least one space on both sides for proper recognition. This spacing rule separates operators from operands.

Q74

Which statement is correct about Table in SNOBOL?

A) Table is indexed by table name.
B) Table is indexed by table size.
C) Table is indexed by the key.
D) Table is indexed by number.

AI Explanation

In SNOBOL, tables store and retrieve values using keys as indexes. Each key is associated with a corresponding value in the table.

Q75

One of the significant feature associated with SNOBOL is ________.

A) Allows String manipulation operation only
B) Explicit Variable declaration
C) Mixing arithmetic and string operations
D) Performing arithmetic operation separately

AI Explanation

A significant feature of SNOBOL is its ability to combine arithmetic operations with string manipulation. This flexibility made it powerful for text processing tasks while still supporting computations.

Q76

For string manipulation, SNOBOL does not use:

A) Regular Expressions
B) Keywords
C) Operators
D) Variables

AI Explanation

SNOBOL does not use regular expressions for string manipulation. Instead, it uses its own pattern matching system with operators, keywords, and variables.
