Example of basic pointer to struct in C Language and operators.

#include <stdio.h>
#include <stdlib.h>

typedef struct myType{
    int x;
    int y;
} miTipo;

int main(void){
    miTipo *z = NULL;
    z = calloc(1,sizeof(miTipo));
    z -> x = 10;
    (*z).y = 15;
    printf("primero: %i, segundo: %i\n", z->x , (*z).y);
    free(z);
    return 0;
}
