Thread: Pointer to an array : string

Hello,

I only have intermediate knowledge in c.
I'm learning some advanced topics about pointers in c,
Below is the program that confuses me

Code:

#include<stdio.h>

int main(void){

    //section 1

    char str1[]="Hello";
    printf("%d, %d, %d, %s\n",&str1,&str1[0], str1, str1);
    printf("\n");
    
    //section 2

    char*str2;
    str2 ="Goodbye";
    printf("%d, %d, %s\n",&str2, str2, str2);
    printf("\n");

    //section 3

    char*string[3];

    string[0]="zero";
    string[1]="one";
    string[2]="two";

    printf("%d, %d, %d, %d, %s\n",&string, string,&string[0], string[0], string[0]);
    printf("%d, %d, %d, %d, %s\n",&string, string,&string[1], string[1], string[1]);
    printf("%d, %d, %d, %d, %s\n",&string, string,&string[2], string[2], string[2]);
    printf("\n");
    system("pause");
}

OUTPUT :

In section 1

Code:

char str1[]="Hello";
    printf("%d, %d, %d, %s\n",&str1,&str1[0], str1, str1);
    printf("\n");
//output : 15989136, 15989136, 15989133, Hello

I know address of an array is the address of first element of that array, which is same as the array name

In section 2

Code:

char*str2;
    str2 ="Goodbye";
    printf("%d, %d, %s\n",&str2, str2, str2);
    printf("\n");
//output : 15989124, 2390488, Goodbye

Here str2 is a pointer, which is stored at some place in memory
and &str2 will display that address. Value of str2 is the address at which the string "Goodbye" is stored

I understand up to this part. But third section confuses me,

Code:

char*string[3];

    string[0]="zero";
    string[1]="one";
    string[2]="two";

    printf("%d, %d, %d, %d, %s\n",&string, string,&string[0], string[0], string[0]);
    printf("%d, %d, %d, %d, %s\n",&string, string,&string[1], string[1], string[1]);
    printf("%d, %d, %d, %d, %s\n",&string, string,&string[2], string[2], string[2]);
    printf("\n");

//output:
//15989104, 15989104, 15989104, 2390852, zero
//15989104, 15989104, 15989108, 2391020, one
//15989104, 15989104, 15989112, 2390840, two

which shows the address of zero, one, two??
What each value in output represents??


Thanks
