Will I have memory leak problem?

[snie]

I define a class CTest

class CTest
{
public:
DcmDataset *dataset;
DcmFileFormat fileformat;

CTest()
{
dataset = fileformat.getDataset();
}

~CTest()
{
delete dataset; //free memory at heap associated to this pointer
}
};


and in main function, I delare

main()
{
CTest *test = new CTest;
//adding other lines if needed
delete test; //free memory at heap assocaited to this pointer
}

Problem:
It is encountered the problem of "Unhandled exception at 0x0050d297 in testfolder2.exe: 0xC0000005: Access violation reading location 0xfeeefeee."

Question:
1) If I only remove the "delete dataset" line in the deconstuctor, or if I only remove "delete test" line in main function, there is no error in run-time, but I wonder if there is memory leak assocaited with it.

2) If I replace "delete dataset" by "delete fileformat.getAndRemoveDataset()", no error in run-time, does getAndRemoveDataset free mmeory?

Thanks,

snie

Since you did not create the DcmDataset with new() you should not delete it anyway. This is done automatically by the destructor of DcmFileFormat.
