  • 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.

    Princeton University Computer Science 217: Introduction to Programming Systems Data Types in C 1 Goals of C Designers wanted C to: But also: Support system programming Support application programming Be low-level Be portable Be easy for people to handle Be easy for computers to handle • Conflicting goals on multiple dimensions! • Result: different design decisions than Java 2 Primitive Data Types • integer data types • floating-point data types • pointer data types • no character data type (use small integer types instead) • no character string data type (use arrays of small ints instead) • no logical or boolean data types (use integers instead) For “under the hood” details, look back at the “number systems” lecture from last week 3 Integer Data Types Integer types of various sizes: signed char, short, int, long • char is 1 byte • Number of bits per byte is unspecified! (but in the 21st century, pretty safe to assume it’s 8) • Sizes of other integer types not fully specified but constrained: • int was intended to be “natural word size” • 2 ≤ sizeof(short) ≤ sizeof(int) ≤ sizeof(long) On ArmLab: • Natural word size: 8 bytes (“64-bit machine”) • char: 1 byte • short: 2 bytes • int: 4 bytes (compatibility with widespread 32-bit code) • long: 8 bytes What decisions did the designers of Java make? 4 Integer Literals • Decimal: 123 • Octal: 0173 = 123 • Hexadecimal: 0x7B = 123 • Use "L" suffix to indicate long literal • No suffix to indicate short literal; instead must use cast Examples • int: 123, 0173, 0x7B • long: 123L, 0173L, 0x7BL • short:

This requirement is not used in the core wording (Tweaks of [5.13.3.3.1] may be needed), nor in the library wording, and therefore does not seem useful, so it was not added in the new wording. This will not have any impact on existing implementations. Unicode in raw string delimiters Falls out of the wording change. should we? New terminology Basic character set Formerly basic source character set. Represent the set of abstract (non-coded) characters in the graphic subset of the ASCII character set. The term ”source” has been dropped because the source code encoding is not observable nor relevant past phase 1.

  • String Class in C++
    String Class in C++ The standard C++ library provides a string class type that supports all the operations mentioned above, additionally much more functionality. We will study this class in C++ Standard Library but for now let us check following example: At this point, you may not understand this example because so far we have not discussed Classes and Objects. So can have a look and proceed until you have understanding on Object Oriented Concepts. #include <iostream> #include <string> using namespace std; int main () { string str1 = "Hello"; string str2 = "World"; string str3; int len ; // copy str1 into str3 str3 = str1; cout << "str3 : " << str3 << endl; // concatenates str1 and str2 str3 = str1 + str2; cout << "str1 + str2 : " << str3 << endl; // total lenghth of str3 after concatenation len = str3.size(); cout << "str3.size() : " << len << endl; return 0; } When the above code is compiled and executed, it produces result something as follows: str3 : Hello str1 + str2 : HelloWorld str3.size() : 10 cin and strings The extraction operator can be used on cin to get strings of characters in the same way as with fundamental data types: 1 string mystring; 2 cin >> mystring; However, cin extraction always considers spaces (whitespaces, tabs, new-line...) as terminating the value being extracted, and thus extracting a string means to always extract a single word, not a phrase or an entire sentence. To get an entire line from cin, there exists a function, called getline, that takes the stream (cin) as first argument, and the string variable as second. For example: 1 // cin with strings What's your name? Homer Simpson E 2 #include <iostream> Hello Homer Simpson.

  • The Char Type ASCII Encoding Manipulating Characters Reading A
    The char Type ASCII Encoding • ASCII ( American Standard Code for Information Interchange) • Specifies mapping of 128 characters to integers 0..127. • The characters encoded include: • The C type char stores small integers. I upper and lower case English letters: A-Z and a-z • It is 8 bits (almost always). I digits: 0-9 • char guaranteed able to represent integers 0 .. +127. I common punctuation symbols I special non-printing characters: e.g newline and space. • char mostly used to store ASCII character codes. • You don’t have to memorize ASCII codes • Don’t use char for individual variables, only arrays Single quotes give you the ASCII code for a character: • Only use char for characters. printf("%d", ’a’); // prints 97 • Even if a numeric variable is only use for the values 0..9, use printf("%d", ’A’); // prints 65 the type int for the variable. printf("%d", ’0’); // prints 48 printf("%d",’’+ ’\n’); // prints 42 (32 + 10) • Don’t put ASCII codes in your program - use single quotes instead. Manipulating Characters Reading a Character - getchar C provides library functions for reading and writing characters The ASCII codes for the digits, the upper case letters and lower • getchar reads a byte from standard input. case letters are contiguous. • getchar returns an int This allows some simple programming patterns: • getchar returns a special value (EOF usually -1) if it can not // check for lowercase read a byte. if (c >= ’a’&&c <= ’z’){ • Otherwise getchar returns an integer (0..255) inclusive. ... • If standard input is a terminal or text file this likely be an ASCII code.

Computer science has long recognized the importance of strings, but it has not adapted a standard for their implementation. We find, therefore, that a string created in Pascal differs from a string created in C.

    ATSC Program IDd System Information Protocol for Temsuial BroadcIst IDd cable 12123197 Additional information may be carried by descriptors which may be placed in the descriptor loop after the basic information. The Virtual Channel Table may be segmented into as many as 256 sections.
