What are some examples of structs and functions in C?

Can you give me some examples of structs and functions in C?

Sure! In C, a struct is a user-defined data type that allows you to combine data items of different kinds. For example:

struct Person {
    char name[50];
    int age;
};

And a function can be defined to work with this struct. Here's an example function that prints a person's details:

void printPerson(struct Person p) {
    printf("Name: %s, Age: %d\n", p.name, p.age);
}

How do I create an instance of the struct and call the function?

You can create an instance of the struct like this:

struct Person person1;
strcpy(person1.name, "Alice");
person1.age = 30;

Then, you can call the function like this:

printPerson(person1);

What if I want to use pointers with structs?

You can use pointers to structs by defining a pointer to the struct type. For example:

struct Person *ptr = &person1;
printPerson(*ptr);
