c - Strcmp pointer from integer without cast

I'm trying to compare two character and see which one is lexicographic longer and sorting by it problem is I'm not sure how to compare single character I tried doing it with strcmp like

struct example
{
 char code;
}
if (strcmp(i->code, j->code) < 0)
    return 1;

warning: passing argument 1 of astrcmpa makes pointer from integer without a cast

warning: passing argument 2 of astrcmpa makes pointer from integer without a cast

I know that strcmp is for strings, should I just malloc and make the char code into a string instead, or is there another way to compare single characters?

char is an integer type.

You compare char objects using the relational and equality operators (<, ==, etc.).
