airport air(1,2,3); //an airport constructor ofstream myfile; myfile.open("rishab",ios::app||ios::binary); myfile.write((char*)air,sizeof(airport); myfile.close(); Such commands are called multiple times in my program to get info of many airports. Basically the binary file is full of airports. I need to read all these airports into an array later on. How do I read the file so that I get the array of airports. Apologies if this question is too basic. I am in high school learning about pointers and shortest path graphs. Dmitry Ledentsov What you are trying to do is serialization. This way of

I'm using ifstream::read to read a file, ifstream ifs("a.txt"); char buf[1024]; ifs.read(buf, 1024); But a.txt's size might be less than 1000 bytes , so how am I supposed to know how many bytes have been read from ifs ? You can get the amount of characters extracted by the last operation with std::ifstream::gcount : ifstream ifs("a.txt"); char buf[1024]; ifs.read(buf, 1024); size_t extracted = ifs.gcount(); or ifstream ifs("a.txt"); char buf[1024]; size_t extracted = ifs.read(buf, 1024).gcount(); since read(...) returns *this . 来源： https://stackoverflow.com/questions/11720880/ifstreamread

Im asking this because i am having trouble understanding sector aligned reading when we are reading raw device. Lets assume whe are in a Windows machined, and we are using the ReadFile() C function to read x bytes from a device. I know we can only read sector aligned data, but recently i discovered the SetFilePointer() function, that allow us to put a pointer in x bytes of the device we have previously opened with CreateFile() . My question is, if we need to read sector aligned data, if we use SetFilePointer() for example like this: SetFilePointer(device, 12, NULL, FILE_BEGIN); (device is a

I am trying to manipulate json file data in powershell and write it back to the file. Even before the manipulation, when I just read from the file, convert it to Json object in powershell and write it back to the file, some characters are being replaced by some codes. Following is my code: $jsonFileData = Get-Content $jsonFileLocation $jsonObject = $jsonFileData | ConvertFrom-Json ... (Modify jsonObject) # Commented out this code to write back the same object $jsonFileDataToWrite = $jsonObject | ConvertTo-Json $jsonFileDataToWrite | Out-File $jsonFileLocation Some characters are being replaced

I am creating a child process, and reading its output. My code works fine when the child process creates output ( cmd /c echo Hello World ), however ReadFile will hang if process does not create output ( cmd /c echo Hello World > output.txt ). I am only reading after the process has terminated. Am I doing something horribly wrong? Is there anyway to do this with synchronous mode, or do I have to use asynchronous mode? All of this is happening in a seperate thread, so I dont think asynchronous mode would offer any benefit to me, unless it is the only way to get this to work. Thanks a lot!
