    DEV-C++ made program crashes when run from outside the ide

    When I click on the compile/run icons in the upper left corner of the devcpp ide my program runs fine. But when i run my program from outside the editor it crashes by just double clicking on it (the exe icon), it crashes.

    I think I know where the problem is but I don't understand it. My program reads text files and then acts upon what values it finds in them. When I hard code all the values in and completely comment out the readfile code the program runs fine when I double clicking on the exe icon.

    I don't understand why using fstream only works for me if i click the compile&run/run icon in the editor and crashes if i try to run the program without the editor.

    Thank you for reading this and your help/comments.

    When you run your program from Dev-C++ the "current" directory is probably different than when you double click on the executable. So, it is possible that the file cannot be found when you couble-click but it can be found when you run from the IDE.

    Try using a full path to the input file and see if it still has an issue.

    And write your program so that it doesn't crash when it can't open the file. Make it write a proper error message instead.
    All the buzzt!
