It refers to a place in your code where names or variable have meaning.
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
a unique item identifier means what?
Isn't keyward isn't identifier.
identifier is a letter , digit.
No. Identifier is a scientific name for the name.Variables, functions, types, etc -- each have an identifier.
Describe the concept of Scope :Incomputer programming, ascopeis the context within acomputer programin which avariable nameor other identifier is valid and can be used, or within which adeclarationhas effect. Outside of the scope of a variable name, the variable's value may still be stored, and may even be accessible in some way, but the name does not refer to it; that is, the name is notboundto the variable's storage
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.
How many times larger the image in the scope appears. A 4 power scope makes the image 4 times larger.

It's short for service set identifier
An attribute used as a unique identifier but not qualifying for it. A good example would be "Name" attribute in "Kid" entity - it's not unique, there can be other kids with the same name. I hope that helped anyone.
a unique item identifier means what?
If the identifier you want to pass is an ordinary identifier, pass it as the address of... function(&identifier); If the identifier you want to pass is an array identifier, pass its name... function(arrayname);
Isn't keyward isn't identifier.
Identifier....
A N D is not an identifier as it has spaces in between each letter. A valid identifier DOES NOT have space in it.
identifier is a letter , digit.
