Introduction
This error often occurs in C++ coding, when the compiler encounters a C++ statement that is trying to call a class which has not been declared. In other words, it means that a “Close” object has not been declared in the appropriate scope.
Explanation
When the compiler is looking for a declared object that is referred to a code statement, it does not find it because it has not been declared. When the compiler fails to find the declared object, the compiler returns an error that reads “Close was not declared in this scope”.
Example
To give a brief overview of this situation let’s look at the following code snippet as an example:
int main()
{
Close close;
return 0;
}
In this example, the compiler is expecting to encounter a "Close" object but it doesn't find it within this scope so the compiler returns an error.
Solution
The solution to this error is to declare the class “Close” before the compiler expects to encounter it in the code.
