hello fellow programmers.

I am having an anoying problem with a Contact book i am making. As the title of this thread suggests i am getting that error but only when i call for a specific function in the program called void search(). All the other functions in the class Adressbok excecute. This all worked fine until today when i was working on it and made some changes this message popped up. Tried to change back to make it work but it just doesnt want to.

I am a bit of a beginner att c++ so dont be to harsh about my code and this is not all finished yet if some parts look strange. Also when I run the debugger a window pops up called Disassebly with the text

This doesnt mean anything to me but i hope this can help you help me solve the problem.

I have many annoying problems with this program...or my compiler has

What compiler do you use? the two first errors can be ignored i was just trying something out in the while loop it should say (!fil.eof()). I dont understand these errors, any idea what they mean?

The main problem is that you need to get rid of header stdlib.h it corrupts the call to getline. One simple error is that your file in the search function should be of type "ifstream" not "ofstream", calling a getline on an ofstream will likely lead to an abnormal termination (usually due to two exceptions being thrown simultaneously, or worse).

With the above changes, I ran your program and it mostly works. I would also take out the line 70 (för där finns ingen tom rad melan personer i filen).

Thanks mike for the tips but i did all that and for some reasong I still got the error, but I managed to solve it somehow. I copied the code and started a new projekt and pasted it. Now it works perfectly. Dont really understand. Hopefully it will work from now on thanks all

That error seems to be caused by this code

int pos = Namn.find (' ');
string efternamn = Namn.substr(pos, 10);

Anyone know why?
