char sentence[SIZE], *tokenPtr;
cout << "Enter a sentence:\n";

cout << "\nThe sentence in Pig Latin is:\n";

while ( tokenPtr!=NULL ) {
printLatinWord( tokenPtr );
tokenPtr = strtok_s( NULL, " ",NULL );
//if ( tokenPtr )

cout << '.' << endl;
return 0;
}

void printLatinWord( char const * const wordPtr )

int len = strlen( wordPtr );
for (int i = 1; i < len; ++i )
cout << *( wordPtr + i );
cout << *wordPtr << "ay";
