CSE 240 MIDTERM QUESTIONS AND ANSWERS

100% CORRECT | GRADED A+




When evaluating a programming language the category Reusability

describes: -✔✔ This concept asks how tied down a language is to a

particular platform, can code be distributed easily and can libraries be

made and shared

Autocode and FORTRAN are considered to be the first high-level

programming languages. -✔✔ True

There was an early focus on efficiency due to early programmable

computers being themselves fairly inefficent being limited in power and

storage. -✔✔ True

With over 500 programming languages in the world, the best way approach

to learning languages is to focus on memorizing syntax and structure. Then

learn languages with simimlar syntaxes and structures. -✔✔ False

What is the major improvement of structured programming languages over

the earlier programming languages? -✔✔ Removing Go to statement from

the language.

,What programming language characteristics impact the readability of the

programs written in this language? -✔✔ Data Structures, Syntax Design,

Control Structures

What programming paradigm does Fortran belong to? -✔✔ Imperative

In contrast to Web 1.0, what is the key function of Web 2.0? -✔✔ Web is

the computing platform

Event-driven computing paradigm is to -✔✔ define a set of events and

write an event handler for each event.

von Neumann Architecture is -✔✔ A state based programming structure

which loads and interprets instructions from memory into action

Event-driven computing paradigm is to -✔✔ define a set of events and

write an event handler for each event.

If your program was designed to print "Hello World" ten (10) times, but

during execution, it printed eleven (11) times. What type of error is it? -✔✔

Semantics Error

Given this snippet of code in C,



char alpha = 'a';

int numeric = alpha + 10;

,which of the following statement is correct: -✔✔ Syntactically correct, but

contextually incorrect.

For the following BNF ruleset, which are terminal symbols? (Check all that

apply.)



<char> ::= a | b | c | ... | x | y | z

<identifier> ::= <char> | <char> <identifer> -✔✔ y, a

Which commands (constructs) do NOT have a loop when expressed in

syntax graphs? Select all that apply -✔✔ while (condition) do {statements;}



if-then-else



for ( <init-expr>; <test-expr>; <increment-expr> ) {<statements>}

If a program contains an error that divides a number by zero at the

execution time. This error is a -✔✔ Semantic Error

Given:



Very Simple Programming Language (VSPL)

, <char> ::= a | b | c | ... | z | 0 | 1 | ... | 9



<operator> ::= + | - | * | / | % | < | > | == | >= | <=



<variable> ::= <char> | <char> <variable>



<expr> ::= <variable> <operator> <variable> | ( <expr> ) <operator> (

<expr> )



<assign> ::= <variable> = <expr>;



<statements> ::= <assign> | <assign> <statements>




The following is valid:

myvar = (x + y) * (a - c); -✔✔ true

Given:
