 </code>
+One way to remember this is "const modifies the thing immediately following it." In the case of <code c++>int *const myPtr = &x;</code> ''const'' modifies ''myPtr'', meaning the value of ''myPtr'' is constant. In the case of <code c++>const int *myPtr = &x;</code> ''const'' modifies ''int'', meaning the value of the ''int'' is constant.
