Unhandled exception at 0x7c92a958 in...Access violation writing location 0x00030fb0.
Code runs fine for awhile and then breaks in first for loop between Counter2 = 150 and Counter2 = 450 then throws the error:
Unhandled exception at 0x009810ab in Sim HW5.exe: 0xC0000005: Access violation writing location 0x00000000.
Any ideas why?

Could you give us a rough idea of what exactly your code is doing?
