Can anyone tell me why my scan isn't working?

I'm new to structs and pointers and I can't see what's wrong with this code:

struct {
    int id;
    char* name;
} cap[50];

void xep() {
    int i, n;
    scanf("%d", &n);
    for (i = 0; i < n; i++) {
        cap[i].id = i;
        scanf("%c", cap[i].name);
        printf("%d %s\n", cap[i].id, cap[i].name);
    }
}

When calling the xep function in main, it only prints:

    0 (null)
    1 (null)
    2 (null)

Like it ignores everything I input after n. Any ideas?

char* name is a pointer, but you haven't allocated any memory to it. Either give it a fixed size char name[100] or alloc some memory. Your scanf is just getting 1 character, you probably want %s (string) instead of %c (character)
