    Issues while using Dev C++ on Vista

    Hello All,
    I am using Dev C++ 5.0 to code a C program in Windows Vista.However,whenever I have pointers in my program the program can't execute.When I try to run the .exe file I get an error that the .exe file has stopped working.However, if the program doesn't have pointers I am able to run the .exe file.I have no idea why this is coming.Any help would be greatly appreciated.

    Two possibilities:
    • You have written a broken program.
    • There's something wrong with Dev-C++ specific to pointers.

    I would put the probabilities at 95% for the first and 5% for the second. (There are definitely things wrong with Dev-C++, and I didn't know they even tried to release 5.0 and bloodshed.net no longer exists so I can't check, but I know of nothing specific to pointers.)

    Does this same code work under (say) gcc, VS, code::blocks, etc? Post the code and we'll look at it.

    Dev-C++ has a very old version of mingw, use Code::Blocks instead

    Thanks for the replies.I am sorry,the version which I am using is 4.9.9.2
    I have not tried to run the code on any other software.
    Here is the attached code file: charptrex.cpp

    Also can I run C programs on Code::Blocks or VS? I tried using VC++ but it didn't allow me to write C programs.

    I tried using Code::Blocks but I am getting the same error when I run the program.Is it in anyway related to VS-2008 installed on my system?

    Visual Studio kinda-sorta has a C compiler in it. They don't really advertise the fact, but if you load up a .c file in a project, and play "God Save the Queen" on the kazoo* while compiling, it will compile it in C.

    Your program compiles-ish. There is a warning when you try to print name: "format argument is not a pointer (arg 2)" because you need to print name, and not *name. When I changed that everything worked most beautifully.

    *This is not actually true. There is a switch you need to flip in the settings, though, I think.

    In my experience, even including some pre-alpha-release compilers which were not exactly bug free, the probability of the first case would comfortably exceed 99%.

    There is, however, about a 95% chance that a novice programmer will blame the compiler rather than their own developmental coding skills.

    That is the obvious and likely cause of the crash. printf("%s", *name) interprets the value of the first character of name as if it is a pointer to a string.
    Right 98% of the time, and don't care about the other 3%.
