c - What is unhandled excpetion error mean? -


i writing in visual studio,a c programm , error: unhandled exception @ 0x77dd3e14 in scicomput.exe: 0xc0000005: access violation reading location 0xff630018.

can explain quite absolute beginner mean?

it means trying access segment of memory doesn't "belong" program, i.e. memory haven't allocated, reserved.

usually, causes such errors attempting write read-only memory or dereferencing null-pointers.

"unhandled exception" means haven't provided way program handle errors when occur, crashes.

note: can handle exceptions via try...catch mechanism in c++. http://msdn.microsoft.com/en-us/library/6dekhbbc.aspx c, however, doesn't support this.
