Question

C++ Help. Will rate

So I am reading data from a file telegram.txt and the general format that is on the file is this:

Leslie Knope

1456 Plymouth Street

Pawnee, IN 47408
Amount Owed: $35.50

Tom Haveford

689 Lil Sebastian Avenue

Pawnee, IN 47408
Amount Owed: $11.00

April Ludgate

1123 9th Avenue

Wamapoke, IN 48034
Amount Owed: $18.00

I need to calculate the total of all the amounts owed in the file. and it must work no matter how many amounts owed there are. here is what i have so far that gets the data and displays it. but i cant figure out how to add them together

// Retrieve document and diplay needed values in program

{

   ifstream inputFile;

   string name1,addr1,city1,state1, blankLine;

   int zip1, num_words1;

   // To get this part to work smoothy I had to include the whole path to retrevie the file. but it does work.

   inputFile.open("TelegramData.txt");

   if (inputFile.fail())

   {

       cout << "Error opening file. ";

   }

   else

   {

       //Process the file.

   }

       while (!inputFile.eof())

   {

       getline (inputFile, name1);

       getline (inputFile, addr1);

       inputFile >> city1;

       inputFile >> state1;

       inputFile >> zip1;

       inputFile >> num_words1;

       blocks = (num_words1/5*BLOCK_RATE);

       singles = (num_words1 % 5*SINGLE_RATE);

       cost = blocks + singles;

       cout<< name1<<endl;

       cout<< addr1<< endl;

       cout<< city1<< endl;

       cout<< state1<<endl;

       cout<< zip1<< endl;

       cout<< "$"<<setprecision(4)<<showpoint<<cost<<endl;

       cout<< " "<< endl;

       // Get empty separator line and discard it

// Since switching between ">>" and getline() for input, must clear input buffer

inputFile.clear(); // resets stream flags

inputFile.ignore(10,' '); // reads buffer for up to 10 characters, exiting upon read of EOL character

       getline (inputFile, blankLine); // now read the blank line in

   }

   inputFile.close();

       cout<< "The total cost of all telegram bills is: " << cost << endl; //?????? This is where i need help i need a total of all the "cost" numbers in the file

}

Explanation / Answer

Hi, I wrote the code to extract cost part from line.

Since you have not posted whole program, so i did not test it.

{
ifstream inputFile;
string name1,addr1,city1,state1, blankLine, num_words1;
int zip1;

int cost = 0;

// To get this part to work smoothy I had to include the whole path to retrevie the file. but it does work.
inputFile.open("TelegramData.txt");
if (inputFile.fail())
{
cout << "Error opening file. ";
}
else
{
//Process the file.
}
while (!inputFile.eof())
{
getline (inputFile, name1);
getline (inputFile, addr1);
inputFile >> city1;
inputFile >> state1;
inputFile >> zip1;
inputFile.ignore(10,' '); // this is to ignore the line after reading zip code
getline (inputFile, num_words1);

int index = num_words1.find('$'); // finding the index of $
num_words1 = num_words1.substr(index+1, num_words1.length()-index);// finding cost part

int x = (int)atof(num_words1.c_str()); // converting into integer

blocks = (num_words1/5*BLOCK_RATE);
singles = (num_words1 % 5*SINGLE_RATE);
cost = blocks + singles;
cout<< name1<<endl;
cout<< addr1<< endl;
cout<< city1<< endl;
cout<< state1<<endl;
cout<< zip1<< endl;
cout<< "$"<<setprecision(4)<<showpoint<<cost<<endl;
cout<< " "<< endl;
  
// Get empty separator line and discard it
// Since switching between ">>" and getline() for input, must clear input buffer
inputFile.clear(); // resets stream flags
inputFile.ignore(10,' '); // reads buffer for up to 10 characters, exiting upon read of EOL character
getline (inputFile, blankLine); // now read the blank line in
}
  
  
  
inputFile.close();
  
cout<< "The total cost of all telegram bills is: " << cost << endl; //?????? This is where i need help i need a total of all the "cost" numbers in the file
}
