What exactly is the error...?

[steinzfan]

It's a warning about the use of customerInfo (line 239). Is there something I did wrong there?

[firedraco]

Yes, cout doesn't know how to output your structure. You either need to output the stuff yourself or make an overload for operator <<.

[Duthomhas]

Argh! How can you read that? Use some formatting and indentation! I recommend you to a pretty printer.
http://www.softpanorama.org/Utilities/beautifiers.shtml

The error I get is:

a.cpp:239: error: no match for 'operator<<' in 'std::cout << customerInfo[i]'

That is, you are trying to print an entire struct, but you have not provided an operator<<() overload to do it.

In C++, you typically declare types outside the main() function, then instantiate it as you would any other variable. Also, it is typically bad practice to rely on the struct namespace to distinguish your type from a variable.

#include <iostream>
#include <limits>
using namespace std;

// class definitions typically go outside functions
struct pair_t
  {
  int left;
  int right;
  };

// an output operator to display the class
ostream& operator << ( ostream& outs, const pair_t& pair )
  {
  outs << "(" << pair.left << "," << pair.right << ")";
  return outs;
  }

// a little funtion for this example to read an integer
int read_int( const char* prompt, const char* error_message )
  {
  int result;
  cout << prompt << flush;
  for (;;)
    {
    bool ok = (cin >> result);
    cin.clear();
    cin.ignore( numeric_limits <streamsize> ::max(), '\n' );
    if (ok) break;
    cout << error_message << '\n' << prompt << flush;
    }
  return result;
  }

int main()
  {
  // using the class
  pair_t two_random_numbers;
  cout << "Please enter two integer numbers:\n";
  two_random_numbers.left  = read_int( "one> ", "Try again." );
  two_random_numbers.right = read_int( "two> ", "Try again." );
  cout << "You entered the pair: " << two_random_numbers << ".\n";
  return 0;
  }

Hope this helps.

[edit] hmm... can't make chocolate cake and respond to posts at the same time...

Mmmm... smells good... chocolate...
