Arrays und Strings

Worin liegt der Unterschied?

char a[] = "hello";
char *p = "world";

Das macht der Compiler draus

a: | h | e | l | l | o |\0 |

   +-----+     +---+---+---+---+---+---+
p: |  *======> | w | o | r | l | d |\0 |
   +-----+     +---+---+---+---+---+---+

a[3] for the compiler means: start at the location a and move three past it and fetch the char there

p[3] means go to the location p, dereference the value there, move three past it (add three to pointer) and fetch the char there.

a[3] is three places past (the start of) the object named a, while p[3] is three places past the object pointed to by p.

ABER in Funktionen:

void foo(int *a);


void foo(int a[]);

sind äquivalent.

Gleiches gilt hier

void foo(int *a) {
    a[98] = 0xFEADFACE;

void bar(int b[]) {
    *(b+498) = 0xFEADFACE;
int * a; /* pointer to int. points nowhere in paticular right now */
int b[10]; /* array of int. Memory for 10 ints has been allocated on the stack */
foo(a); /* calls foo with parameter `int*` */
foo(b); /* also calls foo with parameter `int*` because here the name b basically
           is a pointer to the first elment of the array */


Pointer auf Memory in Mikrocontrollern (via


Base address of PORTF = 0x40025000
Offset address of GPIODIR = 0x400 //page number 663 TM4C123GH6PM datasheet
GPIOFDIR Physical address =  0x40025000+0x400 = 0x40025400

Pointer-Variable anlegen: Pointer zeigt direkt auf Adresse im Speicher

Unsigned int * GPIO_PORTF_DIR_R = (unsigned int*)0x40025400; 

Pointer derefenzieren (Inhalt an Adresse schreiben, auf die der Zeiger zeigt)


Hier werden die ersten 4 Pins als Ausgang konfiguriert

Alternativ ein Pointer direkt auf GPIO

// write value 0xF0 to GPIOFDIR register
 (* ( ( volatile unsigned int * ) 0x40025400 ) ) = 0xF0; 
//read value GPIOFDIR register memory address and store it in variable data. 
 data =  (* ( ( volatile unsigned int * ) 0x40025400 ) ) ;
#define GPIO_PORTF_DIR_R  (*( ( volatile unsigned int * )0x40025400 ) )
