Study Notes
String Manipulation Functions in Various Programming Languages
- C standard library and C++ string manipulation functions are inherently unsafe and have led to numerous programming errors due to lack of guard against overflowing the destination
- Functions in C string library, such as strcpy, do not know the length of the destination, leading to potential memory overwrite
- C++ supports strings through its standard class library, similar to Java, and due to insecurities of the C string library, C++ programmers should use the string class from the standard library
- In Java, strings are supported by the String class and the StringBuffer class, with values specified through methods of the StringBuffer class
- C# and Ruby include string classes similar to those of Java, while Python has strings as a primitive type with various operations
- Python strings act like arrays of characters and are immutable, similar to Java's String class objects
- In F#, strings are a class with individual characters represented in Unicode UTF-16, and strings can be concatenated with the + operator
- ML treats string as a primitive immutable type with ^ as its concatenation operator and includes functions for substring referencing and getting the size of a string
- Swift's String class supports character strings, with objects being either constants or variables, and the binary + operator used for concatenation
- Pattern-matching operations are included in Perl, JavaScript, Ruby, and PHP, loosely based on mathematical regular expressions and often referred to as regular expressions
- A pattern expression in Perl, JavaScript, Ruby, and PHP can be used to match typical name forms in programming languages and numeric literals
- Design choices for string length include static length strings, limited dynamic length strings, and dynamic length strings, with examples from various programming languages given for each option
