    The variable scope refers to where a given variable can be accessed. Scope rules tell us if an entity (i.e., variable, parameter, and/or function) is visible or accessible at certain places. Places where an entity can be accessed, or visible, is referred as the scope of that entity. The variables defined in a subprogram are generally not visible to the calling routine. Thus, a variable \(x\) in the calling routine is different than a variable \(x\) in the subprogram.
