I cant figure out how to print the correct dollar amount in words. Any help would be greatly appreciated.

Is pasting your assignment here all you plan on doing? We'll need more than that to help you. Best idea is to show us an attempt at creating the class.

[Snick]

I have this so far:

.h file:

#ifndef TEXTVERSIONOFNUMBER_H
#define TEXTVERSIONOFNUMBER_H

#include <iostream>
#include <iomanip>
#include <string>
#include <string.h>
#include <sstream>

class TextVersionOfNumber
{
private:
double amount;

public:
std::string getTextVersionOfNumber();
void setAmount(double _amount);
};

#endif

________________________________________________________
.cpp file:

#include "TextVersionOfNumber.h"

std::string TextVersionOfNumber::getTextVersionOfNumber()
{
std::string one_19[20] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };

std::string twenty_90[10] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

double _amount = amount;

double _amount2 = (amount - (_amount)) * 100;//0

std::string str_one = "";

if (_amount <= 19)
{
str_one = one_19[(int)_amount];
}
else
{
int tens = _amount / 10;
int ones = _amount - (tens * 10);
str_one = one_19[ones] + twenty_90[ones];
}

std::string str_two = "";

if (_amount2 <= 19)
{
str_two = one_19[(int)_amount2];
}
else
{
int tens = _amount2 / 10;
int ones = _amount2 - (tens * 10);
str_two = twenty_90[tens] + one_19[ones];
}

std::string ret_val = str_one + " dollars and " + str_two + " cents";
return ret_val;
}

void TextVersionOfNumber::setAmount(double _amount)
{
amount = _amount;
};

I cant get the program to properly display the $ amount in words

[48T7M4Gy]

What does your main() program look like?

[Snick]

#include <iostream>
#include <iomanip>
#include <string>
#include <string.h>
using namespace std;

#include "TextVersionOfNumber.h"

int main()
{
string date = "03/05/2016", payee = "Maya Tolappa";
TextVersionOfNumber checkAmount;
double testAmounts [] = {0, .01, .25, 12, 12.45, 19, 19.02,
19.45, 20, 20.45,
34, 56.78, 100, 109, 119.78,
450, 678.90, 1000, 1009.45, 1056,
1234, 1567.98,9999, 9999.99};

for(int i=0; i < sizeof(testAmounts)/sizeof(double); i++)
{
double an_amount = testAmounts[i];
checkAmount.setAmount(an_amount);
cout << setprecision(2) << fixed;
cout << setw(60) << right;
cout << "Date: " << date << endl;
cout << "Pay to the order of: " << payee << "\t\t\t";
cout << "$" << an_amount << endl;
cout << checkAmount.getTextVersionOfNumber() << endl;
cout << "---------------------------------------------------------------------\n";
}
return 0;
}

Next question. What output do you get and what's wrong with it?

@Snick

I do notice that in your TextVersionOfNumber function, you are only trying to find the tens and ones, but not hundreds or even the thousands. To get the full check value, you're going to need them.

[48T7M4Gy]

First step: Concentrate on how many cents in the amount and the number of tens and the number of units. Convert those two to a string.

string TextVersionOfNumber::getTextVersionOfNumber()
{
    string one_19[20] =
    {
        "", "one", "two", "three", "four", "five", "six", "seven",
        "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen",
        "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"
    };
    
    string twenty_90[10] =
    {
        "", "", "twenty", "thirty", "forty", "fifty",
        "sixty", "seventy", "eighty", "ninety"
    };
    
    //STEP 1 - CENTS
    string cents_str = " and ";
    
    int cents = 100 * amount - (int)amount * 100;
    if( cents > 0)
    {
        int ten_cents = cents/10;
        int single_cents = cents % 10;
        cents_str += twenty_90[ten_cents] + '-' + one_19[single_cents];
    }
    else cents_str += "zero";
    
    cents_str += " cents";
    
    return cents_str;
}
