Get specific byte from M68k ram address with C language

问题

Through the IDA disassembler I've reached this address:

0010FD74  00 00 00 00 00 00 03 00  00 00 00 00 82 03 80 02

Now I need, given the address to get particular bytes; for example the 7th position where there is "03". I've tried using C language to do this:

char *dummycharacter;
*dummycharacter = *(char*)0x10FD74;

Now if I try to access 7th value with this:

dummycharacter[6]

I don't get 0x03…where am I going wrong?

You're trying to assign the value dummycharacter points to (which is pretty much nowhere, since it's not initialized). Try dummycharacter = (char*)0x10FD74;.
