A custom string class that implements strings in the C/C++ environment without NULL termination. It is a proper object that contains the string data and its length. Using these, both read and write methods are provided, as well as other expected string commands, such as upcasing, downcasing, or character indexing.
An improvement for this exercise would be to incorporate more string methods, such as those exemplified in the Python string class: https://docs.python.org/3/library/string.html
This project does not attempt to provide an improvement
over C strings or the C++ string library. This is purely for
pedagogical purposes.
This is an update to my CISP 430 Data Structures class assignment from American River College taught by the great David Fox.
String ( ) // Empty String default constructor
String (char) // Character String constructor
String (const char*) // Character array String constructor
String (const String& s) // Copy constructor
unsigned len ( ) const // String length
int index (char) const // Find character index
void upcase (unsigned first, unsigned last) // Uppercase String within range
void downcase (unsigned first, unsigned last) // Lowercase String within range
void togglecase (unsigned first, unsigned last) // Toggle case within range
friend std::ostream& operator<< (std::ostream&, const String&) // cout << String
friend std::istream& operator>> (std::istream&, String&) // cin >> String
char operator[] (unsigned) const // Reference access
char& operator[] (unsigned) // Copy access
String& operator= (const String&) // Assign new String
String& operator+= (const String&) // Assign concatenated String
friend String operator+ (const String&, const String&) // Concat two Strings
friend String operator+ (const String&, char) // Concat a String and character
friend String operator+ (const String&, const char*) // Concat a String and C-string
friend String operator+ (char, const String&) // Concat a character and String
friend String operator+ (const char*, const String&) // Concat a C-string and String
All argument permutations in concatenation are repeated here, also.
friend bool operator== (const String&, const String&) // Equality
friend bool operator!= (const String&, const String&) // Non-Equality
friend bool operator< (const String&, const String&) // Less-than Inequality
friend bool operator> (const String&, const String&) // Greater-than Inequality
friend bool operator<= (const String&, const String&) // Less-than or Equailty
friend bool operator>= (const String&, const String&) // Greater-than or Equality
