    Runtime error

    Hello everybody,

    I think i am having a problem with my compiler(or with my logic) since yesterday whenever I use a loop (for, while, do...while) the program gives the error:

    This application has requested the Runtime to terminate it in an unusual way.
    Please contact the application's support team for more information.

    I am using Dev-C++ version 4.9.8.3 on Windows Vista Ultimate.

    I include the source code of my latest confussion:

    Code:
    string ExpandString(string Sentence)
    {
       
       int centerpos;
       
           for(int i=Sentence.size();Sentence.size()<40;i++)
           { 
                  string tinystring=Sentence.substr(centerpos,1);
                  Sentence.insert(centerpos,tinystring);
                  centerpos--;
                  tinystring=Sentence.substr(centerpos,1);
                  Sentence.insert(centerpos,tinystring);
           }
           
           return Sentence;     
    }

    just a wild guess -
    centerpos is used uninitialized (you didn't give it a value before using it)
