Serialise and deserialise vector in binary

Question

I am having problems trying to serialise a vector (std::vector) into a binary format and then correctly deserialise it and be able to read the data. This is my first time us

Answer 1

You're using the address of the vector. What you need/want is the address of the data being held by the vector. Writing, for example, would be something like:

size = example.size();
file.write((char *)&size, sizeof(size));
file.write((char *)&example[0], sizeof(example[0] * size));
