In C ++ we usually refer to two types of scopes: temporary and access. A feature of C ++ is the need to declare the variables that will be used in a program. Those variables are local or locally scoped variables for that function. It is generally not possible, and rarely necessary, to declare two variables with the same name, but there are conditions under which it is possible to do so. For example, in a program, we use a variable called test, and at a certain point we assign a new value to it, but we make a mistake and write the test. See perlsub. The compiler or interpreter doesn't catch the error, it just creates a new variable, and continues as if everything is fine.
