writing float array to file
Author
anyone know a way to write a float array to file without splitting up the floats into characters?
void WriteFloatArray(float *floatArray, int numberOfItems, string filename){ ofstream fileOut(filename.c_str(), ofstream::out | ofstream::trunc | ofstream::binary); fileOut.write((char*)floatArray, numberOfItems * sizeof(float)); fileOut.close();}void ReadFloatArray(float *floatArray, int numberOfItems, string filename){ ifstream fileIn(filename.c_str(), ifstream::in | ifstream::binary); fileIn.read((char*)floatArray, numberOfItems * sizeof(float)); fileIn.close();}For more info, go to www.cplusplus.com and punch "ofstream" or "ifstream" into the quick search.
Edit: fixed a syntax error (oops..).

doesn''t work, data is lost
That should work, there must be some kind of error elsewhere in your program.
