This week we will write our own class from scratch. You are asked to implement a class called Word with two constructors and two member functions, print() and contains().
Below is the code to get you started. HINT - You should not change any of the provided code.
/*

#include <iostream>
#include <fstream>
#include <cstring>
using namespace std;
const int MaxSize = 81;
class Word{
public:
// implement constructors and member functions here
// ...
private:
char theWord[ MaxSize];
};
int main() {
// Step 1
// For a score of 1 implement the constructors
ifstream file;
file.open("words.txt");
char myWord[ MaxSize];
Word wordsArray[ 1000]; // You'll need a default constructor for this to work
int index = 0;
while(file >> myWord){
wordsArray[ index] = Word( myWord); // Call the constructor
index++;
}
// Validate that the file was read:
cout << "The last word in the file is: " << myWord << endl << endl;
// Step 2
// For a score of 2, print all words contained in words.txt.
// You will need to uncomment the code below and implement the print() member function
/*
cout << "All words are: ";
for(int i = 0; i < index; i++){
wordsArray[i].print(); // call the print() member function that prints the C-string
cout << " ";
}
cout << endl << endl;
*/
// Step 3
// For extra credit (score of 3), display only words containing 'x'.
// You will need to uncomment the code below and implement the contains() member function
/*
cout << "Words containing 'x' are: ";
for(int i = 0; i < index; i++){
if( wordsArray[ i].contains('x')) { // call the contains() member function
wordsArray[i].print(); // call the print() member function
cout << " ";
}
}
*/
cout << endl;
return 0;
}// end main()
Step 1 (1 point)
Implement: 1) Default constructor that sets “theWord” to empty C-string; 2) Constructor that takes a C-string as input;
Step 2 (1 point)
Now uncomment code for step 2 in main function, then implement print() method, it prints the C-string that was input in the constructor to the screen.
Step 3 - extra credit (1 point)
Now uncomment code for step 3, then implement contains() method, it takes a char and return a boolean indicating if the C-string contains that char.
