If you're casting between things but do not want to change the bit-pattern (e.g. binary data or pointers), you can also use <code>reinterpret_cast</code>. | If you're casting between things but do not want to change the bit-pattern (e.g. binary data or pointers), you can also use <code>reinterpret_cast</code>. | ||
====References==== | |||
References are accepted or store using <code>&<code>.<br> | |||
For example: | |||
<syntaxhighlight lang="c++"> | |||
void healPerson(Person &person) { | |||
person.health = 100; | |||
} | |||
</syntaxhighlight> | |||
References are like pointers since they do not copy the object except they cannot be null and they cannot be reassigned.<br> | |||
Note that primitives can also be used with references, in which case changes will propagate to the underlying value.<br> | |||
You can also use them as class attributes, initializing them in the constructor's initializer list. | |||
