Please help with the changing PIN number function.
"Account" is a structure type. The structure has first, last, balance, pin, and account number. I am not sure how to get a new pin and make sure it doesn't exist, and then add it to the array that is of type account.

       This option should be executed by calling a function to be defined. 

       The function asks users for the account number, PIN number, and new PIN number. 

       It looks for the account in the array by calling another search function. 

       If the account exists and the PIN is correct, then the PIN number is updated in the array. 

        Otherwise (account inexistent or incorrect PIN), 

        an appropriate error message is displayed.









     //prototype

     void changePinNum(account, int&);



   void changePinNum(account myBank, int& size){

      // The function asks users for the account number, PIN number, and

      //new PIN number. It looks for the account in the array by 

      //calling another search function.

    cout << "Please enter your account number: " << endl;

    int foundIndex= -1;



    do{



      cout << "Please enter your account number: " << endl;

        cin >> myBank[size].accountNumber;

        foundIndex = search(myBank, myBank[size].accountNumber, size);

    }while(foundIndex != -1);





cout << "New PIN:" << endl;

cin >> myBank[size].pin;

}





  // this is the search function in case you needed it 

   int search(int myArray,int searchAccount, int arraySize){



   int index = -1; //where it's found at or -1 if account num isnt found



  for(int i=0; i < arraySize; i++){



       if(myArray[i] == searchAccount)

       {

       index = i;

       }

  }

  return index;



 }
