I don't know what your code looks like since you haven't actually provided any, but the compiler is telling you that you are trying to use an identifier that is not in scope. You may or may not have declared the identifier, but if it is not in scope then it is effectively undeclared. The following example illustrates this: for(int i=0; i<10; ++i) std::cout<<i<<std::endl; i=i+1; // ERROR: Undeclared identifier. i is no longer in scope To resolve this problem, we must move the declaration of i outside of the loop, thus making it accessible both inside and outside of the loop: int i; for(i=0; i<10; ++i) std::cout<<i<<std::endl; i=i+1; // OK

What is an identifier in compiler design?
In compiler design, an identifier is a name used to identify a variable, function, class, or any other user-defined item in a program. Identifiers are crucial for representing data and accessing it during compilation and execution. They must adhere to specific naming conventions, such as starting with a letter or underscore and being followed by alphanumeric characters or underscores, ensuring they are unique within their scope to avoid conflicts. Proper handling of identifiers is essential for symbol tables and scope management in the compilation process.

Is possible to declare a variable in a method and declare it a main?
The same identifier (variable name) may be used for at most one variable in each scope. Each method has its own scope, in addition to the global scope which is accessible from all others. However, each scope would have a different variable than every other scope despite using the same name for it.
