C++ help with getline function with ifstream

So I am writing a program that deals with reading in and writing out to a file. I use the getline() function because some of the lines in the text file may contain multiple elements. I've never had a problem with getline until now. Here's what I got.

The text file looks like this:

  John Smith                       // Client name
  1234 Hollow Lane, Chicago, IL    // Address
  123-45-6789                      // SSN
  Walmart                          // Employer
  58000                            // Income
  2                                // Number of accounts the client has
  1111                             // Account Number
  2222                             // Account Number

And the code like this:

ifstream inFile("ClientInfo.txt");
if(inFile.fail())
{
    cout << "Problem opening file.";
}
else
{
    string name, address, ssn, employer;
    double income;
    int numOfAccount;

    getline(inFile, name);
    getline(inFile, address);
    // I'll stop here because I know this is where it fails.

When I debugged this code, I found that name == "John", instead of name == "John Smith", and Address == "Smith" and so on. Am I doing something wrong. Any help would be much appreciated.

The code you show should work on that file. So something must be different than you think. The most likely culprits are:

  1. The file actually has a newline where you think it only has a space
  2. The code uses inFile >> name where you think it uses getline(inFile,name)

Perhaps you changed something and forgot to save or recompile or you are reading a a different file than you think.

By the way, from your variable declarations it looks like you may be planning to mix getline() calls with extraction operator calls like inFile >> income. Mixing these requires care because the extraction operator leaves behind trailing whitespace that getline() might then read. There's more information near the bottom of this.
