Runtime error when using pointers and Files

[egnaro]

I'm getting a strange crash everytime i try to load a file into a pointer. for example,

fin >> gRecs[i]->ID;
if(fin.fail()) break; //then eof
gRecs = new MeatRecord;
fin >> Tmp;
gRecs->MeatType[i] = eMeatType(Tmp);
fin >> gRecs[i]->MeatCut;
fin >> gRecs[i]->ListPrice;
fin >> gRecs[i]->Amount;

I'm not getting any compile errors and i've declared the pointer correctly.

heres a line from the .txt file

1 1 chops 18.50 50.5

for some strange reason everytime the program gets to loading the file, the whole thing dies. Does anyone have any ideas?

Is this a typo?

gRecs->MeatType[i] = eMeatType(Tmp);


What is the value of i, is it within range for the array gRecs?

[egnaro]

No, it would not be a typo. i would be a part of a loop, which would start at 0 and would increment after each line is read and put into the pointer.

I've tried to have a look at it and it seems that when it gets to the part of reading the gRecs[i]->ID part is when it dies. I've taken this part out and the program seems to work fine. Any ideas on why this is happening?

But shouldn't

gRecs->MeatType[i] = eMeatType(Tmp);

be

gRecs[i]->MeatType = eMeatType(Tmp);

?

What it works if you remove the line that reads ID or if you remove all of the posted code. In the first case check that the data in the file is correct for ID, in the second case like I said check that i is in range for the gRecs array.
