              }
     fclose(customer1); 
}

Its telling me that i have a syntax error at the end of input, which is the above code end.

I tried compiling the above code and got this:
customer1 undeclared
NULL undeclared
det undeclared

Also, your last } is for the switch statement, not for the function.
