Pointers to Structures
The way we can have a pointer pointing to an int, or a pointer pointing to a char, similarly we can have a pointer pointing to a struct. Such pointers are known as ‘structure pointers’.
Let us look at a program that demonstrates the usage of a structure pointer.
Example
int main() {
struct book {
char name[25];
char author[25];
int callno;
};
struct book b1 = { "The C book", "ABC", 2101 };
struct book *ptr;
ptr = &b1;
printf("\n%s %s %d", b1.name, b1.author, b1.callno);
printf("\n%s %s %d", ptr->name, ptr->author, ptr->callno);
getchar();
return 0;
}
