WebIn C++, the file stream classes are designed with the idea that a file should simply be viewed as a stream or array of uninterpreted bytes. For convenience, the "array" of bytes stored in a file is indexed from zero to len-1, where lenis the total number of bytes in the entire file. Each open file has two "positions" associated with it: WebI don't think you've done it as often as you suggest: You are reading a string into an unsigned char - that's not going to fit (in C or C++). You appear to be reading a string into an uninitialized pointer - that's not going to work (in C or C++).
The Basics Of Input/Output Operations In C++ Using Iostream
