 <code>void MyMemberFunc() const;</code>
-When you make a member function <code>const</code>, what you're saying is 'this function will not modify the object on which it is called'. This gives you two benefits: first of all, the compiler will tell you if you unintentionally do something that could modify the object inside of the function, and secondly, it allows you to call that member function even on objects that are <code>const</code>!

 Without the <code>const</code>, the operation would store the value 1 in the variable <code>defcon</code>, then the value of defcon would convert to the boolean value <code>true</code>, and the world would be fucked! This is just a simple example; proper use of <code>const</code> can solidify your code in many ways. This is called 'const-correctness'.
-== Use Cases ==
+== Use Situations ==
 There are a number of different situations where you can use <code>const</code>, and the meaning of the keyword changes somewhat depending on the situation.

+When a variable is declared in this manner, operations that modify the variable will cause a compiler error.

Note that you must assign a const variable a value upon creation, since it will not be possible to assign one afterwards.
