This will write the 32 bit integer value directly to the stream without converting it to a string first. Since you have to use binary, you can store the integer values as binary values in the following way: int i = ques.length() įout.write((const char *) &i, sizeof(i)) You should then be able to read one into a stream with the extraction operator in more or less the same way write works. you will have to change your writing method a bit because you can't just write the string object straight to disk like you were before String option1, option2, option3, option4

I'd rewrite your class in the following way: class Question There is a STL class that handles all of the memory crap for you. Since you're using C++, you don't have to do string manipulation as character arrays. Also, mixing cin and cout and the C style IO functions like gets is asking for trouble, so don't. Kindly see it.because I was unable to do so hereĪre you entering a question or answer that's too long for one of your buffers? I'd bet you are, and it's overrunning the bounds of the class and corrupting the stack. So I would like to ask what the problem can be-> void addques()įout.open('question.txt',ios::app|ios::binary) Ĭhar option1, option2, option3, option4 įor the whole program I pasted my code here Here I am trying to add data through class to a binary file.

After searching on net it seems it is related to memory allocation,pointers etc. I am a beginner in this language and I have encountered this problem.
