Problem with cout

Hi, I have an assignment to create a program that asks the user to input an employee's name, the date and the amount of their paycheck and print out a simulated paycheck. I have almost everything figured out, but I keep getting a compile error. Here is my code:

Code:

#include <iostream>
#include <iomanip>
#include <cctype>
#include <cstring>

using namespace std;

void getInfo();
void printLetter(char *, char *, char *, char *);
void printline(char *line, int &startCount);

bool doAgain();

int main()
	{
	getInfo();
	
	return 0;
	}
void getInfo ()
{
	char fname[20], lname[20],  date[11], amount[9];
	double amt;
	string amtTxt;
	
	 do
	   {
		cout << "Please enter the employee's first name:\n";
		cin >> fname;
		fname[0] = toupper(fname[0]);
		cout << "Please enter the employee's last name:\n";
		cin >> lname;
		lname[0] = toupper(lname[0]);
		cout << "Please enter the amount of the check:\n";
		cin >> amount;
		amt = atof(amount);
		if (amt < 0 || amt > 10000)
		{
			cout << "That is an invalid check amount.  Please try again.\n";
			cout << "Please enter the amount of the check:\n";
			cin >> amount;
		}
		
			cout << "Please enter the date (MM/DD/YYYY):\n";
			cin >> date;
			cout << "Here is the way the check will print\n" << endl << endl;

		printLetter(fname, lname, date, amount);
		} 
	   while (doAgain());
}
void printLetter(char *fname, char *lname, char *date, char *amount)
{
	int position;
	char payee[] = "Pay to the Order of: ";
	char disDate[] = "                                      Date: ";
	char dispAmt[] = " $";
	int dp;
	string pay;
	string amtTxt;
	
	

	pay = amount;
	position = 0; 
	printline(disDate, position);
	cout << right << date << endl << endl;

	
	position = 0; 
	printline(payee, position);
	cout << fname << " " << lname;
	cout  <<  setw(10) << dispAmt <<  setprecision(5) <<   showpoint << atof(amount) << endl << endl;

	dp = pay.find('.');
		if (dp == 4)
		{
			for (int i = 0; i < dp; i++)
			{
				switch (amount[i])
				{
					case '1':

					case '5':
						amtTxt = "Five Thousand ";
						break;
					case '6':
						amtTxt = "Six Thousand ";
						break;
					case '7':
						amtTxt = "Seven Thousand ";
						break;
					case '8':
						amtTxt = "Eight Thousand ";
						break;			
					case '9':
						amtTxt = "Nine Thousand ";
						break;	
						
				}
			}	
		}

		if (dp == 3)
		{
			for (int i = 1; i < dp; i++)
			{
				switch (amount[i])
				{
					case '1':
						amtTxt.append("One Hundred ");

						break;	
						
				}
			}	
		}
		if (dp == 2)
		{
			for (int i = 2; i < dp; i++)
			{
				switch (amount[i])
				{

						break;			
					case '9':
						amtTxt.append("Nine ");
						break;	
						
				}
			}	
		}
				cout << amtTxt << "and " << pay.substr(dp) << " cents\n";
}

void printline(char *line, int &startCount)
{
	int charCount = 0;

	if (startCount >= 70) 
	{                     
		cout << "\n";     
		startCount = 0;   
	}

	
	while (line[charCount] != '\0')
	{
		if (startCount >= 60 && line[charCount] == ' ')
		{
			cout << "          \n";  
			charCount++;             
			startCount = 0;
		}
		if (startCount == 0)
		{
			cout << "	";  
			startCount = 10;
		}
		cout.put(line[charCount]); 
		charCount++;               
		startCount++;             
	}
}


bool doAgain()
{
	char again;
	do
	{
		cout << "Do you want to run the program again (Y/N)? ";
		cin >> again;
		again = toupper(again);
	} while (again != 'Y' && again != 'N');
	if (again == 'Y')
	{
		system("CLS");
		return true;
	}
	else
	{
		cout << "Thank you!!!\nHave a nice day!!!" << endl;
		return false;
	}
}

I get one warning and one error:

Code:

checkwriter.cpp(81) : warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data

checkwriter.cpp(231) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

It looks like the << after cout is causing an error, but in my book you can use a cout statement with a string data type so I am not sure what the problem is. Can anyone help me?

Thanks

What compiler are you using?? It compiles perfectly with Borland.

If you are using the string class, you have to #include <string>. I don't see anything in your current code that requires <cstring>, which is for C-style string functions like strcpy and strlen, so you can just change that to <string>. Don't worry about the warning for now. To be technically correct dp should be a string::size_type, but it doesn't really matter in this program.

Is there a reason you aren't using the C++ string class the entire time? There really isn't a need for C style strings here.
