Error in statement "for"

[nhatnamtamtra]

I get an error when i code C++. I used statement "for" . But when i debug, the program don't exit the loop and I see the notice appear in below. I want to know what is it? And how to fix it. I'm Vietnamese, i'm not good at English. I hope you can understand.

The notice:

Unhandled exception at 0x002DB886 in test.exe: 0xC0000005: Access violation reading location 0xFDFDFDFD.

Well, it looks as though you're trying to de-reference a pointer that has an invalid value (0xFDFDFDFD).
