C++ Programming

I have finished the code but there's one error which shows that "strcpy" might be unsafe. Consider using strcpy_s instead. I've tried that but it's not working probably because I didn't implement it correctly. I am posting my code below. It'd be really helpful if you could fix all the strcpy errors and post it below. Thank you.

Text.cpp:

#include #include #include #include #include "Text.h"

Text::Text ( const char *charSeq ) { bufferSize = strlen(charSeq) + 1; buffer = new char[bufferSize]; strcpy(buffer, charSeq); }

Text::Text ( const Text &other ) { bufferSize = other.bufferSize; buffer = new char[bufferSize]; strcpy(buffer, other.buffer); }

void Text::operator = ( const Text &other ) { int len = other.bufferSize; if (len > bufferSize) { delete[] buffer; bufferSize = other.bufferSize; buffer = new char[bufferSize]; } strcpy(buffer, other.buffer); }

Text::~Text () { delete[] buffer; }

int Text::getLength () const { return bufferSize - 1; }

char Text::operator [] ( int n ) const { // check if n is out of range first return 0; }

void Text::clear () { buffer[0] = '\0'; }

void Text::showStructure() const

// Outputs the characters in a string. This operation is intended for // testing/debugging purposes only.

{ int j; // Loop counter

for (j = 0; j < bufferSize; j++) cout << j << "\t"; cout << endl; for (j = 0; buffer[j] != '\0'; j++) cout << buffer[j] << "\t"; cout << "\\0" << endl; }

Text Text::toUpper( ) const { Text temp; for (int i = 0; i < bufferSize; i++) { if ((buffer[i] > 96 && (buffer[i] < 123))) { temp.buffer[i] = char(buffer[i] - 32); } } return temp; }

Text Text::toLower( ) const { Text temp; for (int i = 0; i < bufferSize; i++) { if ((buffer[i] > 64 && (buffer[i] < 91))) { temp.buffer[i] = char(buffer[i] + 32); } } return temp; }

bool Text::operator == ( const Text& other ) const { { if (bufferSize == other.getLength()) { if (bufferSize == 0) { return true; } else { for (int i = 0; i < bufferSize; i++) { if (buffer[i] != other.buffer[i]) { return false; } } return true; } } else { return false; } } }

bool Text::operator < ( const Text& other ) const { if (bufferSize < other.getLength()) { return true; } else { return false; } }

bool Text::operator > ( const Text& other ) const { if (bufferSize > other.getLength()) { return true; } else { return false; } }
