What am I doing wrong?

Firstly, my code:

Code:

#include <iostream>
using namespace std;

class text {
	char *str;
public:
	void setText(char *s, bool memUsed);
	//void setText(char *s, bool memUsed);
	char* getText() { return str; }
	int length() { return strlen(str); }
	text(char *s = "Default Constructor") { setText(s, false); cout << "\nConstructing\n"; }
	~text() { delete [] str; cout << "\nDestructing\n"; }
	text(const text &s);
	
	char &letter(int let);
};

void text::setText(char *s, bool memUsed = true)
{
	if(memUsed == true)
	{	
		delete [] str;
	}
	int length = strlen(s) + 1;
	str = new char[length];
	if(!length)
	{
		cout << "Allocation Error";
		exit(1);
	}
	strcpy(str, s);
}

text::text(const text &s)
{
	int length = strlen(s.str) + 1;
	str = new char[length];
	if(!length)
	{
		cout << "Allocation Error";
		exit(1);
	}
	strcpy(str, s.str); 	
	cout << "\nCopy Constructor\n";

}

char &text::letter(int let)
{
	if(let > 0 && let < length())
	{	
		return str[let];
	}
	return str[0];
}


int main()
{
	text one("jason spaceman");
	text two;
	text three = one;
	text ob;


	cout << one;
	cout << two;
	cout << three;
	cout << endl;

	one.letter(0) = 'J';

	cout << one;
	cout << three;
	cout << ob;

	return 0;
}

I have two problems, first when I try to compile the above code, with MS Visual C++, I get the following error:

G:\CPRG6101\Lab8b.cpp(73) : error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class text' (or there is no acceptable conversion)

It gives me an error for each of the "cout <<" parts in main().

Secondly, I want the program to change the first letter of my name (jason spaceman) to 'Jason Spaceman' (from a lowercase j to an uppercase J) and then output it to the screen along with the length of the string. What do I need to add to main() in order to do this?

Thanks for any help.

You need to overload the operator<<() for your class....

Code:

#include <iostream>
#include <string>

class foobar{
	std::string m_str;
public:
	foobar(const std::string& str):m_str(str){}
	
friend std::ostream& operator<<(std::ostream&,const foobar&);
};

std::ostream& operator<<(std::ostream& out,const foobar& f){
	out << f.m_str;
	return out;
}

int main(){

	foobar f("Hello World");
	
	std::cout << f;
}

Here's my updated code:

Code:

#include <iostream>
using namespace std;

class text {
	char *str;
public:
	text(char *s = "Default Constructor") { setText(s, false); }  
	text(const text &s);  
	~text() { delete [] str; }  
	void setText(char *s, bool memalloc);
	char* getText() { return str; }
	int length() { return strlen(str); }
	char &letter(int let);  
	friend ostream& operator<<(ostream &out,const text ob);
	friend istream& operator>>(istream &in, text &ob);
	text operator=(text obj);
	text operator+(text ob);

};

void text::setText(char *s, bool memalloc = true)
{
	if(memalloc == true)
	{	
		delete [] str;
	}
	int length = strlen(s) + 1;
	str = new char[length];
	if(!length)
	{
		cout << "Allocation Error";
		exit(1);
	}
	strcpy(str, s);
}

text::text(const text &s)
{
	int length = strlen(s.str) + 1;
	str = new char[length];
	if(!length)
	{
		cout << "Allocation Error";
		exit(1);
	}
	strcpy(str, s.str); 	


}

char &text::letter(int let)
{
	if(let > 0 && let < length())
	{	
		return str[let];
	}
	return str[0];
}

ostream& operator<<(ostream &out, const text ob)
{

	out << "The String for this object is " << ob.str << endl; 
	return out;
}

istream& operator>>(istream &in, text &ob)
{
	char charTemp[256];
	cout << endl;
	cout << "Enter string: ";
	in >> charTemp;
	ob.setText(charTemp);
	return in;
}

int main()
{
	
	text one("jason spaceman");
	text two;
	text three = one;
	text ob;
	cin >> ob;


	cout << one;
	cout << two;
	cout << three;
	cout << endl;

	one.letter(0) = 'J';

	cout << one;
	cout << three;
	cout << ob;

	return 0;
}

When I output each of the three objects to the screen I also want to output their respective lengths (the length of each string that each object displays). But I'm not sure how to do this. What do I need to add to my cout << statements?

You already have a function which returns the length so you can just go :

cout << one.length() ;
