一、文件的读写如前面所提,流的读写主要有>, get, put, read, write 等操作,ofstream 继承自ostream, ifstream 继承自 istream,故操作函数都是一致的...ios::binary,例如:ofstream fout(“binary.dat”,ios::out | ios::binary); (一)、write成员 函数函数功能:以字节为单位向文件流中写入整块数据...

I'm new to C++ std::stream and I'm making some tests. I have this simple code: int i = 10; char c = 'c'; float f = 30.40f; std::ofstream out("test.txt", std::ios::binary | std::ios::out); if(out.is_open()) { out<<i<<c<<f; out.close(); } As the stream...

std::ostream out = condition ? &std::cout : std::ofstream(filename); 我见过一些不例外的示例,例如来自http://www2.roguewave.com/support/docs/sourcepro/edition9/html/stdlibug/34-2.html的示例: int main(int argc, char *argv[])
