linked list inside switch

[NitaB]

Okay, I have a slight problem here. My final project was pretty much open to anything. We just had to make a proposal and do it. So, I proposed a bank type program. I had it done and in the bag(or so I thought) until I was told to include linked lists somewhere in it. So, I decided to sorta keep track of the deposits in one linked list and keep track of withdrawals in another linked list. However, I keep getting errors that say "jump to case label - crosses initialization of Nodetype newNodePtr". I know it has something to do with me trying to use linked lists inside a switch function. I really do not want to change the format of my entire program. Is there any way around this? My code is below:

//**************************************************************************
//This program simulates the services offered by a bank. The user can make
//deposits, withdraw, check their balance.
//***************************************************************************
#include <iostream>
#include <string>
#include <cstddef> //to access NULL

using namespace std;

struct NodeType;  //forward declaration
typedef NodeType* NodePtr;

struct NodeType
{
  char transaction;
  float amt;
  float total;
  NodePtr  next;
};

void chooseService();
float balance=0.00;
NodePtr  listPtr = NULL;           //external pointer

int main()
{
    string usernameFirst, usernameLast;
    char answer;


   
    cout<<"\n                     ***Welcome to the Bank of AA&J***\n\n\n";
    cout<<"Please enter your name: ";
    cin>>usernameFirst>>usernameLast;
    cout<<"\n\nWelcome "<<usernameFirst<<" "<<usernameLast<<"!"<<endl;
    cout<<"\n";
    chooseService(); 
    
     action:   
     cout<<"\nWould you like to perform another action? (y or n)";
     cin>>answer;
     if(answer=='n')
     {
      cout<<"\nThank you!  Goodbye!\n\n";
      }
     if(answer=='y')
     {
      chooseService();
      goto action;
      }
    system("pause");
    return 0;
}

//***************************************************************************
void chooseService()
{
     char service;
     float add;
     float subtract;
 
     cout<<"\nPlease choose a service: "<<
     "\n             D-to deposit"<<
     "\n             W-to withdraw"<<
     "\n             C-to check balance"<<
     "\n             H-to see account history\n";
    
     cin>>service;
     switch(service)
     {
      case 'D' : cout<<"Enter amount to deposit: $";
                 cin>>add;
                 balance=balance+add;
                 NodePtr newNodePtr=new NodeType;
                 newNodePtr->amt=add;
                 newNodePtr->total=balance;
                 listPtr=newNodePtr;                 
                 break;
      case 'W' : cout<<"Enter amount to withdrawal: $";
                 cin>>subtract;
                 balance=balance-subtract;
                 break;
      case 'C' : cout<<"Your balance is: ";
                 cout<<"$"<<balance;
                 break;
      case 'H' : NodePtr  currNodePtr;
                 currNodePtr = listPtr;
                 while (currNodePtr != NULL)
                 {
	             cout<<"The transaction amount was: $"<< currNodePtr->amt<< endl;
	             cout<<"Balance: $"<<currNodePtr->total<<endl;
	             currNodePtr = currNodePtr -> next;
                 }      
                 break;
      default :  cout<<"error()";
                 break;
      }
     
}

If you take out everything pointer/linked list related, it compiles perfectly. Just need ideas on how to do a linked list inside a switch.

Thanks for any help as usual!

Introduce a new scope {} inside the case, like so ..

switch (service) {
case 'D' :
  { // new scope begins ..
   ... your code here as is ...
  } // .. and ends
case ...

Hey mitrmkar!

Thanks! That was an easy fix. lol!

switch (service) {
case 'D' :
  { // new scope begins ..
