Seriously? You can't find the line in your code that isAuth() and change it to Auth();?

[Denver]

i did that and it now shows me another error
In function `main':
[Linker error] undefined reference to `Userchange()'
[Linker error] undefined reference to `Members()'
[Linker error] undefined reference to `Passchange()'
[Linker error] undefined reference to `Auth()'
ld returned 1 exit status

Functions must be declared OUTSIDE the main function and BEFORE they are implemented

[Moschops]

Here is the start of your code, properly indented:

#include <iostream.h>
#include <conio.h>
#include<fstream.h>
#include <process.h>
int main()
{
  int ch;
  char x;
  do
  {

    cout <<"Hello And Welcome To Dsz Cinemas\n";
    cout <<"Please Type In The Number Of Your Choice\n";
    cout <<"1. Booking Tickets\n";
     cout <<"2. Latest Updates\n";
    cout <<"3. Gold Membership\n";
    cout <<"4. Credits\n";
    cin >>ch;
    system("cls");

    if (ch==3)

    {
  
      using namespace std;

      void Auth(); // what is this doing here? 
      void Members(); // what is this doing here? 
      void Userchange(); // what is this doing here? 
      void Passchange(); // what is this doing here? 

      string inuser;
      string inpass;
      string user;
      int num = 0;
	  int ch;
	  char pass[BUFSIZ];
	  int i = 0;
	  string com;

	  main()  // Is this ANOTHER function called main? What are you doing?
      {

Your code goes on and on with functions being declared and defined inside other functions and repeated calls to main (which is BAD - do NOT call main yourself) and various other disasters.

Indent your code. Like I have above.
Indent. Your. Code.

You will then be able to see most of these disasters yourself.

i am new to c++ and have just done about 6 months of learning!
those codes is what i have copied from some blogs to make a cinema booking.
so if u would kindly make the necessary changes and print it here i will b thankful

this is the change i made and i got linker errors for

[Denver]

wat do you mean by indented?

[Moschops]

Here is some code that is not indented:

#include <process.h>
int main()
{
int ch;
char x;

do
{

cout <...

Here is the same code, indented:

#include <process.h>
int main()
{
  int ch;
  char x;

  do
  {

      cout <...

See how you can tell by looking what code is inside what set of braces? This makes it much easier to tell when you have, for example, got your do-while loop wrong, or forgotten to put the closing brace on, or started to define a function inside another function.
