The compiler is free to put it into a non-writable location, resulting in the crash you see. Replacing the declaration with char str[] = "Hello World" should do what you want, putting the string into a modifiable array on the stack. share|improve this answer edited Mar 16 '09 at 23:22 answered Mar 16 '09 at 21:18 Michael 40.4k582118 Your suggestion would be identical to the current code. –Daniel Earwicker Mar 16 '09 at 21:19 char str[] versus char* str results in the string being modifiable. –Michael Mar 16 '09 at 21:21 Here's a couple references to this: iso-9899.info/wiki/S

The code works fine for small matrices but when I go beyond a certain level, the following error pops out: Unhandled exception at 0x77913560 in 3d.exe: 0xC0000005: Access violation writing location 0x0000000000050e14. https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/378429 I am dynamically allocating memory with variables, then deallocating them. The code is very long, longer than 20,000 lines. I want to trace the problem. Before deciding to start this topic, I search the forum and other sources. The "Stack Size" problem has seemed reasonable. I changed reserve size to 200,000,000 and commit size 20,000,000. The problem stayed the same with small differences: Unhandled exception at 0x77913560 in 3d.exe: 0xC0000005: Access violation writing location 0x00000000001e0e84. As you can see the code given at the end of the error line is different, I want to know and trace the error. Any kind of help will be appreciated. Thanks ! Emre

Rate this: Please Sign up or sign in to vote. See more: C++ C VC10.0 When running another piece of my new program, the debugging is okay but after that it reported a "Access violation writing location...". Using the breakpoint function, I find that the following function has something wrong: /*variable initialization function*/ void initialize (int temp[MAXLINE], int digit, int nd) { int i; for(i=0; i<=MAXLINE; ++i) { temp[i]=0; } digit=nd=0; } In fact, the error report appears right after the sentence "temp[i]=0;". Could anybody help me with it? I know that access violation means that the data address is not correct but I just cannot figure out what's the problem... Here i post all of the code in this program... I hope someone could tell me what's wrong with it... #include

The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear. First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000. Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000. But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values. The code is very long about 6000 lines so if you want i can post it in here. I know my question is very vague but as the code is too huge to post i am not doing so. I can send u the cpp file by mail if u wish for it. **Wanted to know whether you have come across these kinds of error like when increasing the size causes this bugs to show up. Guys i need serious help. I have been working on this for the past month and now while checking for larger matrix it is not wo
