Data_file.read ( (char *) &data_size, sizeof (data_size)); Web i used the fact that the data () method returns an address you can use for reading and for writing. Web are you a python developer with a c or c++ library you’d like to use from python? Std::cout << size del vector: Web consider using the array module: Such extension modules can do two things. Web here's code for reading:
If so, then python bindings allow you to call functions and pass data from python to c or. Then, when reading it back in, you have to read the number of. For (int i = 0; Web you need to write the length of the vector (number elements) before writing the vector contents. I++) { std::cout << i. #include #include #include #include <<strong>vector</strong>> using bytes = std::vector; Web you are writing to file the vector structure, not its data buffer. Ofstream fout(data.dat, ios::out | ios::binary);. Data() may or may not return nullptr when size() is 0, but. Web use std::vector::data() (c++11 and later only): Web are you a python developer with a c or c++ library you’d like to use from python?
