Thread: Newbie needs help with no match for `* std::string&' operator error

I am receiving the following error when trying to use a pointer to an array that is defined using a structure. If anyone can explain why I'm receiving this error I would really appreciate it.

no match for `* std::string&' operator

Here is the structure that the array is defined in

Code:

#include <iostream>
#include <cstring>
#include <cctype>
#include <cstdlib>
#include <string>

using std::cout;
using std::cin;
using std::endl;
using namespace std;

const int IN_VEHICLE = 100;

struct vehicles_in{
 string inVin;
 int inPassengerCount;
 string inLuxury;
 int inMpg;
 char inType;
}new_vehicle [IN_VEHICLE];

Here are the functions that are using a pointer to the new_vehicle array

Code:

void init_list()
{
  int t;

  for (t=0; t<IN_VEHICLE; t++)*new_vehicle[t].inVin = '\0';
}

void enterNewVehicle()
{
  int i;

  for (i=0;i<IN_VEHICLE; i++)
    if (!*new_vehicle[i].inVin) break;

  if (i==IN_VEHICLE){
  cout << "This list is full.\n";
  return;
}

new_vehicle[t].inVin is a std:string it is initialized to "" in its constructor. -> you don't need the function init_list().
If you want to use it later on to reset the string you could try this way

Code:

void init_list() {
  int t;
  for (t=0; t<IN_VEHICLE; t++) 
     new_vehicle[t].inVin = "";    
}

new_vehicle is an array of vehicles_in's so you must not dereference it

Code:

  for (i=0;i<IN_VEHICLE; i++)
    if ( ! new_vehicle[i].inVin.length() ) break;

Thanks, this helped.
