    Question DEV-C++ compiler message/

    I made my program to reverse digits of a four digit integer value entered by the user. Here is the code:

    Code:
    #include<iostream>
    #include<conio.h>
    
    using std::cout;
    using std::cin;
    using std::endl;
    
    void reverse(int)   // function prototype
    
    int main()
    {
        int num;    // declare varible
        cout<< "Enter any 4 digit integer:";    // prompt the user for input
        cin>> num;    // read input
        reverse(num);    // display reverse order
        
    getch();
    }
    
    void reverse(int value)    // definition    
    {
        int digit1, digit2, digit3, digit4; // declare alias
        digit1=value%10;    // separate digit1
        value/=10;    // divide the remaining 3 digit number
        digit2=value%10;    // separate digit2
        value/=10;    // divide the remaining 2 digit number
        digit3=value%10;    // separate digit3
        value/=10;    // separate the last remaining digit
        digit4=value%10;    // separate digit4
        cout<< digit4 << digit3 << digit2 << digit1;    // reverse order
    }
    I think the code is okeys but the compiler gives me the following message when i press F9.

    'unable to run the program'

    Is there anything wrong with the compiler? Do I have to reinstall it?

    are you running the beta version of Dev. Because I tried to write like 3 different programs and it gave me the same message..so I just saved myself the heart ache and just switched back to
    Dev-C++ 4

    that should do it.
    Which 'a Huh?

    It happened the same thing with me. To fix it, at least it worked for my case, go to Tools->Compiler Options->Directories tab and you'll have four tabs (Binaries, Libraries, C includes, C++ includes). In my case I just have to fix the directory paths to where I installed Dev. It was previously set to wrong directories, so when I compiled, it couldn't find all those includes'. Okay, so try fixing everything under those four tabs.

    Did you try (or even read) my possible solution? No..?
    'Cause that's what I did (reinstalling) the first time but it did not fix it.

    'unable to run the program'
    Google with that keywords. That's how I found the solution for me. You could probably find a solution for yours. So many, many people have the same problem.

    Okay, first of all, there's a few problems with your code:

    1. prototypes should have ';' at the end
    2. it's cout << 1 << 2 << 3 << 4 not cout << 4 << 3 << 2 << 1

    The code works perfectly fine on my Dev C++4.9.8.0, so i dunno wat's wrong with yours, but here's the code:


    Code:
    #include<iostream>
    #include<conio.h>
    
    using std::cout;
    using std::cin;
    using std::endl;
    
    void reverse(int);   // function prototype
    
    int main()
    {
        int num;    // declare varible
        cout<< "Enter any 4 digit integer:";    // prompt the user for input
        cin>> num;    // read input
        reverse(num);    // display reverse order
        
    getch();
    }
    
    void reverse(int value)    // definition    
    {
        int digit1, digit2, digit3, digit4; // declare alias
        digit1=value%10;    // separate digit1
        value/=10;    // divide the remaining 3 digit number
        digit2=value%10;    // separate digit2
        value/=10;    // divide the remaining 2 digit number
        digit3=value%10;    // separate digit3
        value/=10;    // separate the last remaining digit
        digit4=value%10;    // separate digit4
        cout<< digit1 << digit2 << digit3 << digit4;    // reverse order
    }

    Actually, the current Dev-C++ 4.9.8.5 "beta" should be better and more stable than Dev-C++ 4, according to some Dev-C++ veterans on their sourceforge forum.

    There probably was some other problem with your Dev-C++ installation.

    Well, read this article.

    That's also why it is usually good to post your full compile log.
