Does the problem arise from allocating the memory on...

I have done it like this (with fstream): ...

C is always pretty awkward with strings, but it's usually okay to just allocate a char array of size 256 for your string and be on with it. However, what if you want the function to return a string and you don't know the size, since you will be concatenating strings together dozens or hundreds of times? Obviously something like this ...
