-37- C zero base video Pointer Array array pointers

Pointer array

Pointer array is an array , i.e., an array, each element pointer.

#include <stdio.h>

int main(int argc, char* argv[])
{
    int nValue1 = 1;
    int nValue2 = 2;
    int nValue3 = 3;
    int * nArray[3] = { &nValue1, &nValue2, &nValue3 };

    char* sz1 = "hello";
    char* sz2 = "world";
    char* szArray[2] = { sz1, sz2 };
    return 0;
}

In fact, the second parameter argv main C standard, is an array of pointers.
argv array, each element is a pointer to char type data, and because special conventions C language string in the argv array actually each element points to a string.

Array pointer

Array Pointer is a pointer , i.e. a pointer to an array.

#include <stdio.h>

int main(int argc, char* argv[])
{
    char szBuff[4] = { 1, 2, 3, 4 };
    char(* pArray)[4] = &szBuff;
    return 0;
}

Array Pointer applications, primarily in conjunction with a two-dimensional array can be made by the pointer, "line by line" Change Address:

#include <stdio.h>

int main(int argc, char* argv[])
{
    char szBuff[2][4] = { 1, 2, 3, 4 };
    char(* pArray)[4] = &szBuff[0];
    printf("%p\r\n", &szBuff[0][0]);
    printf("%p\r\n", pArray);
    printf("%p\r\n", &szBuff[1][0]);
    printf("%p\r\n", pArray + 1);
    return 0;
}
