Question

SpeechAnalyst

The purpose of this assignment is to practice using strings and C-strings. Your task is to create a class that counts words (by looking for spaces) and sentences (by looking for periods). The data will either come in dribs-and-drabs. Use the infamous operator "<<" to output the data seen so far. Because std::string is a class, I'd recommend you use it to store the text information that has been entered through calls to addData and addStringData.

Implementation Details	Sample Driver
SpeechAnalyst SpeechAnalyst( ); void clear( ); // resets everything... void addData( char * stuff ); void addStringData( std::string stuff ); int getNumberOfWords( ) const; int getNumberOfSentences( ) const; friend ostream& operator << ( ostream& outs, const SpeechAnalyst & sa ); // prints the data seen so far! std::string myData;	SpeechAnalyst sa; cout << sa << endl; std::string speech( "Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal." ); sa.addStringData( speech ); cout << sa << endl; sa.clear(); char * data = new char[ 50 ]; strcpy( data, "Muffin says Hello." ); sa.addData( data ); cout << sa << endl; sa.addData( data ); cout << sa << endl;
	Sample Output
	No data to print out.... Data has 29 words and 1 sentence. Data has 3 words and 1 sentence. Data has 6 words and 2 sentences.

HINT: You may add additional methods to the SpeechAnalyst class as long as you implement those defined in the original class definition.
