  • C Strings and Pointers
    Software Design Lecture Notes Prof. Stewart Weiss C Strings and Pointers C Strings and Pointers Motivation The C++ string class makes it easy to create and manipulate string data, and is a good thing to learn when rst starting to program in C++ because it allows you to work with string data without understanding much about why it works or what goes on behind the scenes. You can declare and initialize strings, read data into them, append to them, get their size, and do other kinds of useful things with them. However, it is at least as important to know how to work with another type of string, the C string. The C string has its detractors, some of whom have well-founded criticism of it. But much of the negative image of the maligned C string comes from its abuse by lazy programmers and hackers. Because C strings are found in so much legacy code, you cannot call yourself a C++ programmer unless you understand them. Even more important, C++'s input/output library is harder to use when it comes to input validation, whereas the C input/output library, which works entirely with C strings, is easy to use, robust, and powerful. In addition, the C++ main() function has, in addition to the prototype int main() the more important prototype int main ( int argc, char* argv[] ) and this latter form is in fact, a prototype whose second argument is an array of C strings. If you ever want to write a program that obtains the command line arguments entered by its user, you need to know how to use C strings.

  • String Objects: the String Class Library
    String Objects: The string class library Lecture 12 COP 3014 Spring 2018 March 26, 2018 C-strings vs. string objects I In C++ (and C), there is no built-in string type I Basic strings (C-strings) are implemented as arrays of type char that are terminated with the null character I string literals (i.e. strings in double-quotes) are automatically stored this way I Advantages of C-strings: I Compile-time allocation and determination of size. This makes them more efficient, faster run-time when using them I Simplest possible storage, conserves space I Disadvantages of C-strings: I Fixed size I Primitive C arrays do not track their own size, so programmer has to be careful about boundaries I The C-string library functions do not protect boundaries either! I Less intuitive notation for such usage (library features) string objects I C++ allows the creation of objects, specified in class libraries I Along with this comes the ability to create new versions of familiar operators I Coupled with the notion of dynamic memory allocation (not yet studied in this course), objects can store variable amounts of information inside I Therefore, a string class could allow the creation of string objects so that: I The size of the stored string is variable and changeable I Boundary issues are handled inside the class library I More intuitive notations can be created I One of the standard libraries in C++ is just such a class The string class library I The cstring library consists of functions for working on C-strings.

Your assignments in this class will be evaluated not only on the correctness of your answers, but on your ability to present your ideas clearly and logically. You should always explain how you arrived at your conclusions, using mathematically sound reasoning. Whether you use formal proof techniques or write a more informal argument for why something is true, your answers should always be well-supported. Your goal should be to convince the reader that your results and methods are sound. For questions that only ask for diagrams, justifications are not required but highly recommended.

  • Regular Expressions
    Regular Expressions A regular expression describes a language using three operations. Regular Expressions A regular expression (RE) describes a language. It uses the three regular operations. These are called union/or, concatenation and star. Brackets ( and ) are used for grouping, just as in normal math. Goddard 2: 2 Union The symbol + means union or or. Example: 0 + 1 means either a zero or a one. Goddard 2: 3 Concatenation The concatenation of two REs is obtained by writing the one after the other. Example: (0 + 1) 0 corresponds to f00; 10g. (0 + 1)(0 + ") corresponds to f00; 0; 10; 1g. Goddard 2: 4 Star The symbol ∗ is pronounced star and means zero or more copies. Example: a∗ corresponds to any string of a’s: f"; a; aa; aaa;:::g. ∗ (0 + 1) corresponds to all binary strings. Goddard 2: 5 Example An RE for the language of all binary strings of length at least 2 that begin and end in the same symbol. Goddard 2: 6 Example An RE for the language of all binary strings of length at least 2 that begin and end in the same symbol. ∗ ∗ 0(0 + 1) 0 + 1(0 + 1) 1 Note precedence of regular operators: star al- ways refers to smallest piece it can, or to largest piece it can. Goddard 2: 7 Example Consider the regular expression ∗ ∗ ((0 + 1) 1 + ")(00) 00 Goddard 2: 8 Example Consider the regular expression ∗ ∗ ((0 + 1) 1 + ")(00) 00 This RE is for the set of all binary strings that end with an even nonzero number of 0’s.

(Or: do we believe that string_view(null_char_ptr) is more likely to match programmer intent or to represent a bug?) 6 How many functions are there today that accept const char* and (by contract or not) allow for null values? 7 Which view of string_view design speaks to you: is it a lightweight string, or is it a pointer-and-length pair, or is it a mix of the two? 7 Which provides more net value to the C++ community? 7 Could we add a new type such as nullable_string_view? 7 Will the proposed changes negatively affect performance? 8 Proposed Wording 8 Change History 9 Acknowledgements 9 Abstract This paper proposes modifying the requirements of basic_string_view(const charT* str) ​ such that it becomes well-defined for null pointers, both at compile-time and at runtime. Background What is a string_view? ​ ​ The string_view type has shipped in C++17. Substantive redesign is likely out of the question ​ ​ without getting into P0684 territory and long-term refactoring plans.

  • Regular Expressions in Pharo
    Chapter 1 Regular Expressions in Pharo with the participation of: Oscar Nierstrasz ([email protected]) Regular expressions are widely used in many scripting languages such as Perl, Python and Ruby. They are useful to identify strings that match a certain pattern, to check that input conforms to an expected format, and to rewrite strings to new formats. Pharo also supports regular expressions due to the Regex package contributed by Vassili Bykov. Regex is installed by default in Pharo. A regular expression1 is a template that matches a set of strings. For example, the regular expression 'h.*o' will match the strings 'ho', 'hiho' and 'hello', but it will not match 'hi' or 'yo'. We can see this in Pharo as follows: 'ho' matchesRegex: 'h.*o' −→ true 'hiho' matchesRegex: 'h.*o' −→ true 'hello' matchesRegex: 'h.*o' −→ true 'hi' matchesRegex: 'h.*o' −→ false 'yo' matchesRegex: 'h.*o' −→ false In this chapter we will start with a small tutorial example in which we will develop a couple of classes to generate a very simple site map for a web site. We will use regular expressions (i) to identify HTML files, (ii) to strip the full path name of a file down to just the file name, (iii) to extract the ti- tle of each web page for the site map, and (iv) to generate a relative path from the root directory of the web site to the HTML files it contains. After we complete the tutorial example, we will provide a more complete descrip- tion of the Regex package, based largely on Vassili Bykov’s documentation 1http://en.wikipedia.org/wiki/Regular_expression 2 Regular Expressions in Pharo provided in the package.2 1.1 Tutorial example — generating a site map Our job is to write a simple application that will generate a site map for a web site that we have stored locally on our hard drive.
