Unable to list out stack - c

Question

I am trying to do a push, pop and list function into a stack. It should first push 4 strings(I write them as array because %s cannot run properly), and then pop 3 strings out, and list the last string. However, the code can't run properly. Can somebody helps me?
This is the code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include<conio.h>
#define MAX 4
int point = -1;
char item[MAX][20];
void push(char item[point])
{
point++;
};
void pop(char item[point])
{
point--;
};
void list()
{
if (point > -1) {
for (int i = 0; i <= point; i++) {
printf("%c\n", item[point-i]);
}
}
};
int main()
{
//AB01
char arrA[4] = {'A','B','0','1'};
for(int i=0;i<4;i++)
{
printf("%c",arrA[i]);
}
point++;
printf("\n");
push (arrA[4]);
//AB02
char arrB[4] = {'A','B','0','2'};
for(int i=0;i<4;i++)
{
printf("%c",arrB[i]);
}
point++;
push (arrB[4]);
printf("\n");
//AB03
char arrC[4] = {'A','B','0','3'};
for(int i=0;i<4;i++)
{
printf("%c",arrC[i]);
}
point++;
push (arrC[4]);
printf("\n");
//AB04
char arrD[4] = {'A','B','0','4'};
for(int i=0;i<4;i++)
{
printf("%c",arrD[i]);
}
point++;
push (arrD[4]);
printf("\n");
//Delete 3 strings
pop(arrA[point]);
pop(arrB[point]);
pop(arrC[point]);
list();
return 0;
}
It seems that the list cannot run properly. Because I'd used arrays to show the strings, and it makes me unable to list properly(because I used an array again in the list(), and then it becomes 2 array). What should I do if I want to let my strings(characters in array) being list?
