    okk
    For this you have to test as many cases...and try to guess the logic....

    and if you want a solution
    then post here maximum 3 test cases

    I will try

    Well....guys i think its leading you to confusion.

    Ok....let me tell u.First of all i have a blank screen in my DOS prompt.
    It just ask for a username.

    After entering the username it asks for password.Now coz i don't know the password i enter some text and it shows that the password is wrong.

    So it is a C/C++ program and i have only .exe file.I think the problem is clear now!!!!!!!......

    but to solve this problem
    You have to give us some test cases
    simply give us output here
    how you enter input
    and what computer shows you everything???This is problem of encryption/decryption
    we have to analyze the output to help you
    Thanks

    no way to get c/c++ code back from .exe file but you can get assembly code by memory hacking or try to use decompiler
