ifstream read double from file

[o1pz6Up4]

I'm trying to read a line of information from a file and I'm running into a problem while reading the double. I need the program to read and display the number 5693.3 and it's displaying some weird long number including a symbol. Any help is greatly appreciated!

This is the line of information:
John H. Doe 1001 H 5693.3

The command window outputs this:
John H. Doe 1001 H 5693.3-858993460╠-9.25596e+61

#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>

using namespace std;

void readBillingRecord(ifstream& fin, string& name, int& accNum, char& type, double& usage);

int main()
{
	string billingDataFile = "Water Bill Records.txt";
	string billingReportFile = "Water Bill Report.txt";
	ifstream fin;
	ofstream fout;
	string name;
	int accNum;
	char type; 
	double usage;

	fin.open(billingDataFile);
	if (fin.fail())
		{
			cout << "\nError opening " << billingDataFile << " file for reading. \nProgram Terminated. \n";
			system("pause");
			return EXIT_FAILURE;
		}
    readBillingRecord(fin, name, accNum, type, usage);
	system("pause");
	return 0;
}

void readBillingRecord(ifstream& fin, string& name, int& accNum, char& type, double& usage)
{
	fin >> name >> accNum >> type >> usage;
	cout << name << accNum << type << usage << endl;
}

getline reads the whole line.

Yes, I see where I went wrong. However, now I'm stuck on how to get the name stored in a string including white space characters, and then get the rest of the input stored separately as an int, char, and double?

Edit: Here is the entire file I need to read and extract data from line by line. I need the name extraction to work for all types of names.

John H. Doe 1001 H 5693.3
James Randolph, Jr. 3333 H 1000.0
Sara Lawrence-Smith 2456 H 3999999.5
Good Time Industries 4678 C 10000000.1
Big Business, Inc. 6757 I 12500849.9
Mom and Pop Shop 5002 C 4000000.7
The O'Leary Company 8022 I 9999999.9

Alright, so far I've gotten this piece of program to read the lines and separate the pieces into the data types I need. However, it is creating and unhandled exception at accNum = stoi(m[2]);

Here is the modified function code that I changed in the above program:

void readBillingRecord(ifstream& fin, string& name, int& accNum, char& type, double& usage)
{
	string line;
	regex r{ R"(([\D]*)(\d*) (\w) (\d*.?\d*))" };
	smatch m;
	while (getline(fin, line)) 
	{
		regex_match(line, m, r);

		name = m[1];
		accNum = stoi(m[2]);
		type = string{m[3]}[0];
		usage = stod(m[4]);

		cout << name << accNum << type << usage << endl;
	}
}

Make sure that the lines does not contain spaces at the end, or change your regex to handle it properly.

You should check the return value of regex_match before using the matches, or use a try-catch block.
