The whole code is incomplete?
Why am i getting the error?

The code you posted (badly) is incomplete.
Therefore it is not "whole"

Thanks… Tom… :slight_smile:

That type of error is usually caused by improper syntax in a preceding line, such as forgetting a closing bracket, parentheses, quote mark, etc.

You are using a struct variable named 'patientname' but you did not declare that variable properly. The 'typedef' keyword just sets up a synonym for for a type. In this case the synonym for 'struct patient' is 'patientname'. That makes it a type, not a variable.

 typedef struct patient patientname;

What you need is to declare a variable of type 'struct patient':

  struct patient patientname;

This would also work:

 patient patientname;
struct patient
  char Lastname; 
  char Firstname;
  char symptoms;

Using a single character for each of those is going to be confusing in the long run.
