Editing C syntax (section)

====Referencing====
When a non-static pointer is declared, it has an unspecified value associated with it. The address associated with such a pointer must be changed by assignment prior to using it. In the following example, ''ptr'' is set so that it points to the data associated with the variable ''a'':

<syntaxhighlight lang=C>
int a = 0;
int *ptr = &a;
</syntaxhighlight>

In order to accomplish this, the "address-of" operator (unary {{code|&}}) is used. It produces the memory location of the data object that follows.
