What sort of compiler are you using? Try using as he said. Or try deleting it and rewrite it. And try checking your char reply; hope that help. The following code don’t compile in VC. This issue is read only, because it has been in Closed–Fixed state for over 90 days. It was closed for 147 days. We have directed your feedback to the appropriate engineering team for further evaluation.

any suggestions on how to fix these errors?thanks.!
'identifier' : undeclared identifier
The compiler can't find the declaration for an identifier. There are many possible causes for this error. The most common causes of C2065 are that the identifier hasn't been declared, the identifier is misspelled, the header where the identifier is declared is not included in the file, or the identifier is missing a scope qualifier, for example,
cout
instead of std::cout
. For more information on declarations in C++, see Declarations and Definitions (C++).Here are some common issues and solutions in greater detail.
The identifier is undeclared
If the identifier is a variable or a function name, you must declare it before it can be used. A function declaration must also include the types of its parameters before the function can be used. If the variable is declared using
auto
, the compiler must be able to infer the type from its initializer.If the identifier is a member of a class or struct, or declared in a namespace, it must be qualified by the class or struct name, or the namespace name, when used outside the struct, class, or namespace scope. Alternatively, the namespace must be brought into scope by a
using
directive such as using namespace std;
, or the member name must be brought into scope by a using
declaration, such as using std::string;
. Otherwise, the unqualified name is considered to be an undeclared identifier in the current scope.If the identifier is the tag for a user-defined type, for example, a
class
or struct
, the type of the tag must be declared before it can be used. For example, the declaration struct SomeStruct { /*..*/ };
must exist before you can declare a variable SomeStruct myStruct;
in your code.Electri6ity vst crack. If the identifier is a type alias, the type must be declared by using a
using
declaration or typedef
before it can be used. https://veryskiey885.weebly.com/nexus-2-vst-free-download-windows.html. For example, you must declare using my_flags = std::ios_base::fmtflags;
before you can use my_flags
as a type alias for std::ios_base::fmtflags
.Example: misspelled identifier
This error commonly occurs when the identifier name is misspelled, or the identifier uses the wrong uppercase and lowercase letters. The name in the declaration must exactly match the name you use.
Example: use an unscoped identifier
This error can occur if your identifier is not properly scoped. If you see C2065 when you use
cout
, this is the cause. When C++ Standard Library functions and operators are not fully qualified by namespace, or you have not brought the std
namespace into the current scope by using a using
directive, the compiler can't find them. To fix this issue, you must either fully qualify the identifier names, or specify the namespace with the using
directive.This example fails to compile because
cout
and endl
are defined in the std
namespace:Identifiers that are declared inside of
class
, struct
, or enum class
types must also be qualified by the name of their enclosing scope when you use them outside of that scope.Example: precompiled header isn't first
This error can occur if you put any preprocessor directives, such as #include, #define, or #pragma, before the #include of a precompiled header file. If your source file uses a precompiled header file (that is, if it's compiled by using the /Yu compiler option) then all preprocessor directives before the precompiled header file are ignored.
This example fails to compile because
cout
and endl
are defined in the <iostream> header, which is ignored because it is included before the precompiled header file. To build this example, create all three files, then compile stdafx.cpp, then compile C2065_pch.cpp.To fix this issue, add the #include of <iostream> into the precompiled header file, or move it after the precompiled header file is included in your source file.

Example: missing header file
You have not included the header file that declares the identifier. Make sure the file that contains the declaration for the identifier is included in every source file that uses it.
Another possible cause is if you use an initializer list without including the <initializer_list> header.
You may see this error in Windows Desktop app source files if you define
VC_EXTRALEAN
, WIN32_LEAN_AND_MEAN
, or WIN32_EXTRA_LEAN
. These preprocessor macros exclude some header files from windows.h and afxv_w32.h to speed compiles. Look in windows.h and afxv_w32.h for an up-to-date description of what's excluded.Example: missing closing quote
This error can occur if you are missing a closing quote after a string constant. This is an easy way to confuse the compiler. Note that the missing closing quote may be several lines before the reported error location.
Example: use iterator outside for loop scope
This error can occur if you declare an iterator variable in a
for
loop, and then you try to use that iterator variable outside the scope of the for
loop. The compiler enables the /Zc:forScope compiler option by default. See Debug Iterator Support for more information.Example: preprocessor removed declaration
Error C2065 Undeclared Identifier
This error can occur if you refer to a function or variable that is in conditionally compiled code that is not compiled for your current configuration. This can also occur if you call a function in a header file that is currently not supported in your build environment. If certain variables or functions are only available when a particular preprocessor macro is defined, make sure the code that calls those functions can only be compiled when the same preprocessor macro is defined. This issue is easy to spot in the IDE, because the declaration for the function is greyed out if the required preprocessor macros are not defined for the current build configuration.
This is an example of code that works when you build in Debug, but not Retail:
Example: C++/CLI type deduction failure
This error can occur when calling a generic function, if the intended type argument cannot be deduced from the parameters used. For more information, see Generic Functions (C++/CLI).
Example: C++/CLI attribute parameters
Visual Studio Cout Undeclared Identifier
