Thread: inputFn with hash not assigning pointer correctly

well, the topic says a bit
getting input from a file
sampe input
<string>flight num <string> city <int>price <string>time

my key is the flight number

i have a DATA node where all my data gets stored via dynamic allocation.

Code:

typedef struct
{
	char flightNum[8];
	char city[20];
	int price;
	int search_count; //used later for heap
	char depTime[6];
}DATA;

and i have a hashed array which is a array of HASH structs.

Code:

typedef struct
{
	void *dataPtr; //this is the pointer that is not being assigned correctly, pointing to DATA, or atleast meant to
	int flag;
}HASH;

now i am trying to print but it doesnt seem like it recognizes the fact that void *dataPtr is pointing to anything

can anyone point out whats going wrong please

Code:

void inputFn(HASH hashAry[],
			 FILE* fpInput)
{
	char dataIn[8];
	int index;
	int i = 0;
	DATA* temp;
	char tempStr[20];
	

	while(fscanf(fpInput,"%s", dataIn) != EOF)

	{	
		index = hashFn(dataIn);

		while(hashAry[index].flag == NOTEMPTY)
		{
			index = CRA(index);
		}
	
		hashAry[index].flag = NOTEMPTY;

		temp = (DATA*)malloc(sizeof(DATA));

		strcpy(temp->flightNum, dataIn);

		fscanf(fpInput, "%s", tempStr);
		strcpy(temp->city, tempStr);

		fscanf(fpInput, "%d", &(temp->price));
		
		fscanf(fpInput,"%s", tempStr);
		strcpy(temp->depTime, tempStr);

		hashAry[index].dataPtr = temp; //i suspect this line doesnt work

		printf("%s\n", temp->flightNum);
		printf("%s\n", hashAry[index].dataPtr->city);

	}

		return;
}

thanks mates
