C++ Pig Latin Lab

This assignment uses pointers to perform something done often in computer applications: the parsing of text to find “words” (i.e., strings delineated by some delimiter).

Write a program that encodes English language phrases into Pig Latin. Pig Latin is a form of coded language often used for amusement. Many variations exist in the methods used to form Pig Latin phrases. Use the following algorithm: to form a Pig Latin phrase from an English language phrase, tokenize the phrase into words with the C++ function strtok_s(). To translate each English word into a Pig Latin word, place the first letter of the English word at the end of the English word and add the letters “ay” after it. Thus, the word “jump” becomes “umpjay,” the word “the” becomes “hetay,” and the word “computer” becomes “omputercay.” Blanks between words remain as blanks. Assume that the English phrase input from the keyboard consists of words separated by blanks, there are no punctuations marks, all words have 2 or more letters, and the input phrase is less than 200 characters. Function printLatinWord() should display each word. Hint: Each time a token is found in a call to strtok_s(), pass the token pointer to function printLatinWord() and print the Pig Latin word.

Your program should allow the user to enter phrases until he or she selects an exit option to quit.

In summary: Create a Pig Latin program to implement this functionality: Prompt the user to enter a sentence. Print out the sentence, and then print out the same sentence in Pig Latin. Repeat this sequence until the user elects to quit.

Description:

In C++, we make use of cstring library to make use of function from C such as strlen() and then we have the function strtoken and strtoken_s(). Please take care of such functions as they will not executing in each and every environment you work.

main.cpp

#include <iostream>

#include <cstring>

using namespace std;

//class that hold strings of PigLatin

class PigLatin

{

//variable to Piglatin form word

private:

char *latin;

public:

//constructor that converts word into PigLatin form

PigLatin(char *word)

{

//get the string length

int i, j = 0, len = strlen(word);

//allocating space

latin = new char[len + 3];

//forming word

for (i = 1; i < len; i++)

{

latin[j] = word[i];

j++;

}

//Adding last characters

latin[j] = word[0];

j++;

latin[j] = 'a';

j++;

latin[j] = 'y';

j++;

latin[j] = '\0';

}

//Function that returns the word in PigLatin form

string getLatin()

{

string str(latin);

return str;

}

//Destructor to deallocate memory

~PigLatin()

{

delete[]latin;

}

};

//Function that receives the char * variable as parameter and prints its PigLatin form

void PrintLatinWord(char *str)

{

//creating an object of PigLatin class

PigLatin obj(str);

//Printing word in PigLatin form

cout << obj.getLatin() << " ";

}

//Main function

int main()

{

int i;

char str[200];

char *pch;

char option;

//Loop till user wants to quit

do

{

//Reading a phrase

cout << "\n\n Enter a sentence to translated:";

cin.getline(str, 200);

//splitting words to tokens

pch = strtok(str, " ");

cout << "\n\t";

//split enter phrase completes

while (pch != NULL)

{

//Passing token

PrintLatinWord(pch);

pch = strtok(NULL, " ");

}

//Reading user option

cout << "\n\n Do you want to enter another sentence? (Y - continue, N - Exit):";

cin >> option;

cin.ignore();

} while (option != 'N' && option != 'n');

cout << endl;

system ("pause");

return 0;

}

Output:
