In the article, it says "The Rust *struct* has a smaller size compared with the C due to the usage of smart pointers instead of allocating item memory inside the *struct*. We use *pahole* to identify that Rust *struct*s use fewer cache lines than their C counterpart."<p>As far as I know, you can also use pointers (not smart ones, that's a C++ thing) inside structs in C, right? Like this:<p><pre><code> struct student
{
char *name;
int age;
char *program;
char *subjects[5];
};</code></pre>
