4. Start Implementing the operations of the Text class
(only the body of methods) 4.1. Implement default
constructor: Text::Text ( const char *charSeq ){} 4.2.
Implement copy constructor: Text::Text ( const Text &other
){} 4.3. Implement operator =: void Text::operator = (
const Text &other ){} 4.4. Implement destructor:
Text::~Text (){} 4.5. Implement getLength(): int
Text::getLength () const {} 4.6. Implement operator []:
char Text::operator [] ( int n ) const {} 4.7. Implement
clear(): void Text::clear () {} 4.8. Implement
showStructure():void Text::showStructure () const {} 5.
Compile your implementation of the Text ADT in the file
Text.cpp and the test program in the file test1.cpp. 6. Test
your implementation using the program in the file
test1.cpp. 7. Implement more methods: 7.1. Implement
toUpper(): Text Text::toUpper( ) const {} 7.2. Implement
toLower(): Text Text::toLower( ) const {} 8. Activate test
1 in the program test1.cpp by changing the definition of
LAB_TEST1 from 0 to 1 in config.h and recompiling. 9.
Implement more operators: 9.1. Implement operator ==:
bool Text::operator == ( const Text& other ) const {} 9.2.
Implement operator <: bool Text::operator < ( const Text&
other ) const {} 9.3. Implement operator >: bo ol
Text::operator > ( const Text& other ) const {}
Solution
#ifndef TEXT_H #define TEXT_H #include #include
using namespace std; class Text { public: //
Constructors and operator= Text ( const char *charSeq
