Lesen einer Anzahl Zeile für Zeile und teilen Sie es auf mehrere Variable in C

Question

samplegame.txt (actual_file)

6 
2 3 3 
11 2 
18 1 
10 3 
22 14 
30 19 
8 16 
12 24 
20 33 

ich will Daten lesen .txt in meine C-Datei program.For jede Zeile trennen sie und speichert sie in der variablen, ich kann in weiteren step.i'm so verwenden versuchen

FILE* file = fopen (argv[1], "r"); 
    int i = 0; 

    fscanf (file, "%d", &i); 
    while (!feof (file)) 
    { 
     //printf ("%d ", i); 
     fscanf (file, "%d", &i); 
    } 
    fclose (file); 

zu verwenden, aber ich habe die ganze Zahl in einer Zeile und kann nicht herausfinden, wie jede Gruppe trennen wie

int board_size = 6 << 1st line 

int minion_box_size = 2; << 2nd line 
int trap_size = 3; 
int trampoline_size = 3; 

int minion_box[minion_box_size] = {11,18}; << 3rd to N line 
int minion_walk[minion_box_size] = {2,1}; 

int trap_position[trap_size] = {10,22,30}; << N+1 to M line 
int trap_end[minion_box_size] = {3,14,19}; 

int trampoline_position[trampoline_size] = {8,12,20}; << M+1 to k line 
int trampoline_jump[trampoline_size] = {16,24,33}; 

Hat jemand einen Vorschlag?

samplegame.txt (erklärt)

______Board_________ 

6  // size of game board 
_____size of each item_________ 
2 3 3  // first number in this line is Minion_box,which means there is 2 Minion_box 
      // Second number is trap_holes,which means there is 3 traps 
      // third number is trampoline,which means there is 3 trampolines 
_____Minion_Box_______ 
// first number  : where the minion_box are 
// Second number : how many step that the minion can walk 
11 2  // the box is in 11th block , minion has aiblity to walk 2 step 
18 1  // the box is in 18th block , minion has ability to walk 1 step 
______Traps__________ 
// first number  : where the traps are 
// Second number : the block you gonna be,after stepping on the trap. 
10 3  // there is a trap hole in the 10th block,step on it and you will fall down 3rd block 
22 14  // a trap hole in the 22th block,fall down to 14th block 
30 19  // a trap hole in the 30th block,fall down to 19th block 
____trampoline_______ 
// first number  : where the trampoline are 
// Second number : the block you gonna be,after stepping on the trampoline. 
8 16  // there is a trampoline in 8th block,if you step on it you will jump to 16th block 
12 24  // trampoline in 12th block,jump to 24th block 
20 33  // trampoline in 20th block,jump to 33th block 

Sorry für schlechtes Englisch und wirklich lange posten, da ich bin nicht gut in Englisch, so versuche ich, um das Beispiel zu zeigen, so viel wie möglich :(

Wenn Sie fgets() und sscanf() eine Datei Zeile für Zeile, eine bessere Nutzung lesen möchten.

char buffer[BUFFER_SIZE]; // with a #define BUFFER_SIZE 1024 or whatever sooner in the code 
int first_value, second_value; 

if (fgets(buffer, BUFFER_SIZE, f) == NULL) 
{ 
    if ferror(f) 
    { 
     perror(""); 
    } 

    exit(1); 
} 

if (sscanf(buffer, "%d %d", &first_value, &second_value) != 2) 
{ 
    fprintf(stderr, "missing value\n"); 
    exit(1); 
}
