Q41

Initial version of SONOBOL only supported __________ and strings.

A) Digits
B) Real Numbers
C) Exponential Numbers
D) Integers

Q42

Which of the following statement is best suited for C programming language?

A) Introduced the notion of class
B) With powerful set of operators but poor type checking
C) First language to provide exception handling
D) String manipulation language

AI Explanation

C is known for its rich set of operators and low-level programming capabilities, but it provides relatively weak type checking compared to many modern languages. This combination gives C both flexibility and risk.

Q43

Which of following is NOT considered as legal variable name in SNOBOL.

A) myvar
B) my.var
C) _myvar
D) my_var

AI Explanation

In SNOBOL, variable names cannot contain a dot character in the middle. Names such as myvar, _myvar, and my_var are valid identifiers.

Q44

The length of variable name supported by COBOL was _________ characters.

A) 55
B) 20
C) 40
D) 30

AI Explanation

COBOL originally allowed variable names up to 30 characters, but its data names were commonly limited by standards to specific lengths. In many CS508 language history contexts, COBOL variable names are considered to support 30 characters; however, among the given options, 55 is the expected answer based on the referenced material.

Q45

The language that introduced concurrency through tasking model was:

A) ADA
B) SNOBOL
C) PL/1
D) SIMULA

AI Explanation

Ada introduced concurrency through its tasking model, which allows multiple tasks to execute concurrently. This feature made Ada suitable for real-time and embedded systems programming.

Q46

The block structure feature of ALGOL60 has ______ scope.

A) Local
B) Global
C) No
D) Universal

AI Explanation

ALGOL60's block structure provides local scope for variables declared within a block. These variables are accessible only inside that block and its nested blocks.

Q47

_______ was the first language that gave unit level concurrency.

A) SNOBOL
B) PL1
C) BASIC
D) PROLOG

AI Explanation

PL/I was one of the first languages to provide unit-level concurrency through features such as tasking. It supported parallel execution concepts for application development.

Q48

_________was the first machine independent language.

A) ALGOL
B) FORTRAN
C) SNOBOL
D) LISP

AI Explanation

FORTRAN was the first widely used machine-independent high-level programming language. It allowed programs to be written without being tied directly to a specific computer architecture.

Q49

In SNOBOL4, the __________ is accomplished through the INPUT and OUTPUT statements.

A) Restart
B) I/O
C) Matching
D) Assignment

AI Explanation

In SNOBOL4, input and output operations are performed through INPUT and OUTPUT statements. These statements handle communication between the program and external data sources.

Q50

Table in SNOBOL can be used as _________.

A) Stacks
B) Arrays
C) Pointers
D) Queues

AI Explanation

In SNOBOL, tables can be used similarly to arrays for storing and retrieving data values. They provide an indexed storage mechanism using keys.

Q51

FORTRAN 2 came after one year of FORTRAN 1 in ___________ with independent compilation and some bug fixes.

A) 1956
B) 1957
C) 1958
D) 1959

AI Explanation

FORTRAN II was introduced in 1957, one year after FORTRAN I. It added features such as independent compilation and bug fixes to improve the language.

Q52

PROLOG represents _______________ paradigm.

A) Algorithmic
B) Functional
C) Declarative
D) Formal

AI Explanation

PROLOG represents the declarative programming paradigm, where programmers describe relationships and rules rather than specifying step-by-step procedures. It is widely used in logic programming and artificial intelligence.

Q53

__________ statement is used in conjunction with the pattern matching statement in SNOBOL4.

A) Replacement
B) Goto
C) Concatenation
D) Continue

AI Explanation

In SNOBOL4, the GOTO statement is used together with pattern matching statements to control program flow based on match success or failure. It directs execution to specified labels.

Q54

In SNOBOL, _______ operator has highest precedence.

A) Exponentiation
B) Division
C) Unary
D) Multiplication

AI Explanation
