A hidden global variable must be one that has its scope blocked by a local variable of the same name. To access the hidden variable, use the scope resolution operator ::, such as is ::variable_name. If there is another reason for the hidden status, please clarify and restate the question.

Why global variables need to be kept to a minimum?
Polluting the global namespace with variables that have no reason to be global is never a good idea. Aside from anything else, the programmer has no control over what code may access a global, and global variable declarations may be spread over many files or hidden within headers, making it difficult to get an overview of every global. Globals are not necessarily a bad thing; if a concept is global in nature then of course make it global. But don't make variables global in the mistaken belief that it is somehow convenient. If a variable really needs to be shared amongst a specific set of functions then there are far better ways of doing so without making the variable global to all functions. Declaring the variable locally in a function (even the main function as a static variable) and passing it to the functions that operate upon it, or by encapsulating the variable in a class along with the functions that operate upon it are far better options than making a variable globally accessible. Keeping variables as close to the code that operates upon them makes your code easier to both read and maintain.
