Thread: pointer access

hello can someone tells me how did we access the values using :
buffer[i]
as i see from the code it is a pointer an we should use * to accses the value inside the address

code from :

How to copy complete structure in a byte array (character buffer) in C language? - IncludeHelp

Code:

Code:

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

struct Person
{
    char name[20];
    int age;
};

int main()
{
    //structure variable declaratio with initialisation
    struct Person person={"Deniss Ritchie", 60};
    //declare character buffer (byte array)
    unsigned char *buffer=(char*)malloc(sizeof(person));
    int i;
    
    //copying....
    memcpy(buffer,(const unsigned char*)&person,sizeof(person));
    
    //printing..
    printf("Copied byte array is:\n");
    for(i=0;i<sizeof(person);i++)
        printf("%02X",buffer[i]);
    printf("\n");
    
    //freeing memory..
    free(buffer);
    return 0;
}

Output
Copied byte array is:
44 65 6E 69 73 73 20 52 69 74 63 68 69 65 00 00 00 00 00 00 3C 00 00 00
