using structs as kinda classes in C

#include <stdio.h>
#include <string.h>
struct Person {
    char name[100];
    int age;
    void (*connect_methods)(struct Person *);//guess I coudl get rid of this and just use a function but somehow it seems nice to use a methodd to connect other methods, but usig a function would reduce the number of lines of code
    void (*increment_age)(struct Person *);
    void (*print_me)(struct Person *);
};

void increment_age(struct Person *self) {
    self->age++;
}
void print_me(struct Person *self) {
    printf("\nname:%s\nage%i\n",self->name,self->age);
}

void connect_methods(struct Person *self) {
    self->increment_age=&increment_age;
    self->print_me=&print_me;

}
int main(int argc, const char * argv[]) {
    struct Person p1;
    strcpy(p1.name,"Jhon Doe");
    p1.age=22;
    p1.connect_methods=&connect_methods;
    p1.connect_methods(&p1);

    struct Person p2;
    strcpy(p2.name,"Marry Joan");
    p2.age=33;
    p2.connect_methods=&connect_methods;
    p2.connect_methods(&p2);

    p1.increment_age(&p1);
    p1.print_me(&p1);
    p2.increment_age(&p2);
    p2.print_me(&p2);
    printf("end\n");
    return 0;
}
