Problem Set:
14.
Describe
the advantages and disadvantages of some programming environment you have used?
a.
~C~
=Disadvantages=
does not have concept of OOPs(Object Oriented Programming)
There is no runtime checking in C language
=Advantages=
C language has variety of data types and
powerful operators. Due to this, programs written in C language are efficient,
fast and easy to understand.
15. How
do type declaration statements for simple variables affect the readability of a
language, considering that some languages do not require them?
a.
maybe
have affect on readability of a language and user or reader must be found type variables before used the
language
16.
Write
an evaluation of some programming language you know, using the criteria
described in this chapter.
Readability
C has two kinds of structured data types, arrays and records (structs), records can be returned from functions but arrays cannot
Writability
C language has relatively convenient, rather than
cumbersome, ways of specifying computations(For example,the notation count++ is
more convenient and shorter than count = count + 1).
Reliability
In
different compiler c have different option for compiling and running.c give
only the concepts.
17.
Some
programming languages—for example, Pascal—have used the semicolon to separate
statements, while Java uses it to terminate statements.Which of these, in your
opinion, is most natural and least likely to result in syntax errors? Support
your answer.
a.
in
my opinion, the possibility of a second language can result in a syntax errors,
but the java language more or less result in than the pascal syntax errors
because the user is more effective to use a semicolon at the end of the
statement compared with each statement
18.
Many
contemporary languages allow two kinds of comments: one in which delimiters are
used on both ends (multiple-line comments), and one in which a delimiter marks
only the beginning of the comment (online comments). Discuss the advantages and
disadvantages of each of these with respect to our criteria
a.
The
advantage of paired delimiters is that you can
comment out areas of a program. The disadvantage of using only beginning
delimiters is that they must be repeated on every line of a block of comments
