So, I've been trying to implement a dictionary using an array(still haven't written DiDelete function, not relevant right now), but two problems emerged, here's the code:

```
#include <stdio.h>
#include <stdlib.h>
#define MAX 1000

typedef int elementtype;

typedef struct{
    int last;
    elementtype elements[MAX];
}Dictionary;

void DiMakeNull(Dictionary *A)
{
    (*A).last = -1;
}

int DiMember(elementtype x, Dictionary A)
{
    int f,m,l;
    f = 0;
    l = A.last;
    m = (f+l)/2;
    while(f <= l )
    {
        if( A.elements[m] == x) return 1;
        else if( A.elements[m] < x) f = m+1;
        else l = m-1;

        m = (f+l)/2;
    }
    return 0;
}

void DiInsert(elementtype x, Dictionary *A)
{
    int i = 0,j;
    elementtype temp;
    while( ((*A).elements[i] < x) && ((*A).last >= i) )
    {
        i++;
    }
    for(j = i ; j <= (*A).last; j++)
    {
        (*A).elements[j+1] = (*A).elements[j];
    }

    (*A).elements[i] = x;
    (*A).last++;
}

int DiEmpty(Dictionary A)
{
    if(A.last == -1) return 1;
    return 0;
}

void DiPrint(Dictionary A)
{
    int i;
    printf("Dict:\n");
    for(i = 0; i <= A.last; i++)
        printf("%d\n",A.elements[i]);
    printf("End!");
}

```

Question 1: why does DiPrint not work? After giving a Dictionary with confirmed numbers in its' array of elements it prints out random numbers. It seems fairly simple, I don't understand what I've gotten wrong there! 

Question 2: Why is it, that when a function is e.g. 

```
void function(Dictionary *A)

```

can't I use the notation A->last, but insted I have to use (\*A).last

Thanks in advance!

EDIT: main program looks like this:

```
#include <stdio.h>
#include <stdlib.h>
#include "atp_dictionary_pomocu_liste.c"

int main()
{
    Dictionary A;
    DiMakeNull(&A);
    DiInsert(4,&A);
    DiInsert(3,&A);
    DiInsert(32,&A);
    DiPrint(A);
    return 0;
}

```
