Drill 4: Write a test — Structs and function design

#include <stdio.h>

typedef struct {
    const char *slug;
    const char *title;
    int minutes;
} Course;

void print_course(const Course *course) {
    printf("%s (%s) · %d min\n",
           course->title, course->slug, course->minutes);
}

int main(void) {
    Course html = { "html", "HTML Foundations", 120 };
    print_course(&html);
    return 0;
}
