Consider the following variable declarations, some of which are incomplete: const int cip var; int const ipc var const int const cipc_var; In a C++ program named testconst.cpp, test and identify the various characteristics of each of these variables, briefly describing the reasoning for each characteristic: Declare without initialization Assign addresses of constant integers Assign addresses of non-constant integers Modify the address to which the pointer points 'Modify the value at the address that the pointer points to Data type found at the address that the pointer points to
