Variable scopes are related to C++ programming. There are three different places within a program where variable scopes can be declared. These three places include inside a function or block which is called local variables, in the definition of function parameters or formal parameters, or outside of all functions which is called global variables.
A few accurate statements about variable scopes would be that sub-blocks cannot reuse a parent block’s variable name, parallel blocks can use the same variable name, and a variable can be defined at any point in a block.
