Hey ich Probleme habe, indem sie die Elemente auf meinem struct befreienC: Probleme bei Verwendung von Free() auf Structs Elemente, Seltsam Behivor
Langcode
typedef struct bingo
{
char board[5][5];
int* luckNum;
int* boardNum;
} bingo;
void update(bingo *pBingo,int num); //Function that gets a struct, number and checks if he is in the board, if it does he change it to "X"
int main(void)
{
srand(time(NULL));
int i, j, m, k, temp[75], *parr;
bingo player;
//For rellocating them later
if (!(player.luckNum = (int*) malloc(sizeof(int))))
{
printf("ERROR");
}
if (!(player.boardNum = (int*) malloc(sizeof(int))))
{
printf("ERROR");
}
//giving temp values of 1-75
for (i = 0; i < 75; i++)
{
temp[i] = i + 1;
}
//Giving the player board random values of 1-75 without repeating the same number twice
for (i = 0; i < 5; i++) //Passing on the rows
{
for (j = 0; j < 5; j++) //Passing on the collumns

temp[k] = NULL; //NULL as a "flag" that marks the cell as taken (for not taking the same number twice)
player.luckNum=(int*) malloc(sizeof(int)*(i*j+j));
player.luckNum[i*j + j] = player.board[i][j];
}
}
//sets luckNum

}
}
}

}
}
jemand erkennen Warnung kann, was Interrupts die free() -Funktion aus dem Speicher zu befreien ?. Ich bin neu in C und arbeite an diesem Code über gute Tage so leid für meine Unwissenheit über die kostenlose() Funktion, kann mir jemand helfen?
Ein Problem ist, dass man mit malloc zuteilen 'player.luckNum' am Anfang von main und dann in der verschachtelten Schleife (was völlig falsch scheint BTW). –
