+This works fine for simple cases but can cause problems if your application requires additional memory.
+If you need to increase the size of your memory, you must allocate a
 second larger buffer and copy the data to it before you can free the original
 buffer. This increases overall memory usage and causes unnecessary ``memcpy``
 calls. Another solution is to allocate a larger buffer than you initially need.
 However, this isn't an efficient way to handle resources and doesn't solve the
 issue of reallocation when the extra buffer runs out.
