Heres what I got to do My program is getting a couple errors

Heres what I got to do. My program is getting a couple errors.(program at the end of question) I need to have the prototypes stuct then main and then the functions at the bottom . please help. I will post the description with the input.dat file data.

Write a program that declares a struct to store the following data of a NorthEast Bank customer :

Customer last name 10 characters (this will contain no spaces)

Customer type 1 character (valid values : D, E, P)

Checking Account number 4 digits

Savings Account number 4 digits

Credit Card account number 6 digits

Mortgage account number 5 digits

Declare an array of 10 components to store the data of 10 customers. The program must contain a function to input the data from a file (attached) and a function to output all the data. Also, there must be a function to find a customer by name and a function to find a customer by checking account number.

Lastly, a function must output all information for a specific customer.

The program is to load the data from the input file and then present the user with the following menu :

   Welcome to the NEB Customer Lookup

a Lookup customer by checking account and output customer data

b Lookup customer by name account and output customer data

c. Output all customers data

d. Exit program

input.dat file

Solution

I have corrected all the error, you have to use same type of datatype in prototype definitions in the program. Please find the updated code.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void output_customer(int );
char getMenuChoice();
int read_data(struct customer *,string);
void output_data(struct customer *,int);
void lookup_by_name(struct customer *,int);
void lookup_by_checkings_account_number(struct customer *, int);

struct customer{
   string name;
   char type;
   int checkings_account_number;
   int savings_account_number;
   long int credit_card_number;
   long int mortgate_account_number;
};

int main(){
   cout << \"Welcome to the NEB Customer Lookup\" << endl;
   char choice;
   customer *arr = new customer[100];
   int count = read_data(arr,\"input.dat\");
   while(true){
       choice = getMenuChoice();
       if(choice == \'a\')
           lookup_by_checkings_account_number(arr, count);
       else if(choice == \'b\')
           lookup_by_name(arr, count);
       else if(choice == \'c\')
           output_data(arr, count);
       else
           return 0;
   }
   return 0;
}

int read_data(customer *arr, string fileName){
   ifstream in(fileName.c_str());
   int count = 0;
