Hallo Community,
Ich habe mal auf dem PC ein Programm geschrieben, dass Zahlenwerte in einer Verketteten Liste speichert. Ich dachte mir, dass kann der Robby auch nur Zahlen sind witzlos, es müssen schon char-Arrays/Strings sein. Das ganze endete in einem Zeigergewirr mit Strukturgewirr verknüpft. Ich hoffe ihr habt eine Lösung für mein Problem, ich habe 'ne ganze menge Zeit rein investiert.
Code:
#include "asuro.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct knoten {
char wort[16];
struct knoten *next;
};
typedef struct knoten Knoten_t;
typedef struct knoten* KnotenPtr_t;
KnotenPtr_t anfang = NULL;
void einfuegenknoten( KnotenPtr_t neu ) {
KnotenPtr_t hilfZeiger;
if( anfang == NULL ) {
anfang = neu;
neu->next = NULL;
}
else {
hilfZeiger = anfang;
while(hilfZeiger->next != NULL) hilfZeiger = hilfZeiger->next;
hilfZeiger->next = neu;
neu->next = NULL;
}
}
void neuerKnoten(void){
KnotenPtr_t neu = malloc(sizeof(Knoten_t));
if( neu == NULL){
SerWrite("Speicher ist voll/Kein Speicher vorhanden!\n\r",45);
return;
}
SerWrite("Wert für Knoten eingeben:\n\r",26);
do { SerRead(wort[16] ,15,0);
} while( getchar()!='\n');
}
void loescheKnoten(char txt[]){
KnotenPtr_t hilfZeiger1;
KnotenPtr_t hilfZeiger2;
if(anfang != NULL){
char tmp[] = anfang->wort
else if( strcmp(txt[], tmp[]) == 0 ){
hilfZeiger1 = anfang->next;
free(anfang);
anfang = hilfZeiger1;
}
else {
hilfZeiger1 = anfang;
while(hilfZeiger1->next != NULL){
hilfZeiger2 = hilfZeiger1->next;
char tmp2[] = hilfZeiger2->wort[];
if( strcmp( txt[] , tmp2[]) == 0 ){
hilfZeiger1->next = hilfZeiger2->next;
break;
}
}
}
}
}
void knotenAuflisten(void){
KnotenPtr_t hilfZeiger = anfang;
while( hilfZeiger != NULL ){
char out[16] = hilfZeiger->wort[16];
SerWrite(out, 16);
hilfZeiger = hilfZeiger->next;
}
}
int main(void){
while(1){
char wahl[2] = '\0';
char tmp[16];
SerWrite("-a- Neues Wort hinzufügen\n\r", 28)
SerWrite("-b- Wort löschen\n\r",19);
SerWrite("-c- Alle Worte auflisten\n\r",27);
SerWrite("Ihre Wahl:\n\r",13);
SerRead(wahl, 1,0);
if( strcmp(wahl, 'a') == 0){
neuerKnoten();
break;
}
else if(strcmp(wahl, 'b')==0){
SerWrite("Wort zum löschen:\n\r",20);
SerRead(tmp, 15,0);
loescheKnoten(tmp[16]);
break;
}
else if(strcmp(wahl, 'c')==0){
knotenAuflisten();
break;
}
}
return 0;
}
Nun zur Fehlermeldung:
