You should use char *argv[] –ouah Jan 3 '12 at 18:25 add a comment| 7 Answers 7 active oldest votes up vote 30 down vote accepted For one, you can't modify string literals. It's undefined behavior. To fix that you can make str a local array: char str[] = "First string"; Now, you will have a second problem, is that str isn't large enough to hold str2. So you will need to increase the length of it. Otherwise, you will overrun str - which is also undefined behavior. To get around this second problem, you either need to make str at least as long as str2. Or allocate it dynamically: char *str2 = "Second string"; char *str = malloc(strlen(str2) + 1); // Allocate memory // Maybe check for NULL. strcpy(str, str2); // Always remember to free it. free(str); There are other more elegant ways to do this involving VLAs (in C99) and stack allocation, but I won't go into those as their use is somewhat questionable. As @SangeethSaravanaraj pointed out in the comments, everyone missed the #import.

Join them; it only takes a minute: Sign up I am getting bus error in following code up vote 3 down vote favorite 1 I am getting bus error in my code. With this code I am trying to convert numbers to words, but I know that there is a flaw in my logic. http://stackoverflow.com/questions/10729906/i-am-getting-bus-error-in-following-code But before that, when I compile and run this code using g++ in mac, I am trying to make this code run as it is and I am getting a bus error. Any help would be appreciated. When I run the code I get following output. I have debug messages to trace where the error occurs. Enter a number:1234 main 1:numbers are:234 Function1: Number is 234 two two hundred 34Function2: Number is 34 Function3: Number is 34 Bus error: 10 #include challenged and removed. (July 2015) (Learn how and when to remove this template message) In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a https://en.wikipedia.org/wiki/Bus_error process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent bus error to the process that caused the error. SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by a bug in a program's source code.[citation needed] Bus errors may also be raised for certain other paging errors; see below. Contents 1 Causes 1.1 Non-existent bus error 10 address 1.2 Unaligned access 1.3 Paging errors 2 Example 3 References Causes[edit] There are at least three main causes of bus errors: Non-existent address[edit] Software instructs the CPU to read or write a specific physical memory address. Accordingly, the CPU sets this physical address on its address bus and requests all other hardware connected to the CPU to respond with the results, if they answer for this specific address. If no other hardware responds, the CPU raises an exception, stating that the requested physical address is unrecognized by the whole computer system. Note that this only covers physical memory addresses. Trying to access an undefined virtual memory address is generally considered to be a segmentation fault rather than a bus error, though if the MMU is separate, the processor can't tell the difference. Unaligned access[edit] Most CPUs are byte-addressable, where each unique memory address refers to an 8-bit byte. Most CPUs can access individual bytes from each memory address, but they generally cannot access larger units (16 bits, 32 bits, 64 bits and so on) without these units being "aligned" to a specific boundary (the x86 platform being a notablBus Error 10 Gulp
