The `ifstream` class is used for reading from files, `ofstream` is used for writing to files, and `fstream` can be used for both.\n\nHere's a concise example for both reading from and writing to files:\n\n**Writing to a file:**\n```cpp\n#include \n#include // Include the file stream library\n\nint main() {\n std::ofstream outFile(\"example.txt\"); // Create an ofstream object and open the file\n\n if (outFile.is_open()) { // Check if the file has been opened successfully\n outFile << \"Hello, World!\" << std::endl; // Write to the file\n outFile << \"This is another line.\" << std::endl;\n outFile.close(); // Close the file\n } else {\n std::cerr << \"Unable to open file for writing.\" << std::endl;\n }\n\n return 0;\n}\n```\n\n**Reading from a file:**\n```cpp\n#include \n#include // Include the file stream library\n#include // Include the string library\n\nint main() {\n std::ifstream inFile(\"example.txt\"); // Create an ifstream object and open the file\n std::string line;\n\n if (inFile.is_open()) {\n while (std::getline(inFile, line)) { // Read the file line by line\n std::cout << line << std::endl; // Output the line\n }\n inFile.close(); // Close the file once done\n } else {\n std::cerr << \"Unable to open file for reading.\" << std::endl;\n }\n\n return 0;\n}\n```\n\nIn both examples, make sure to replace `\"example.txt\"` with the actual file path you're working with. Checking whether the file stream is open is important to avoid errors when the file cannot be opened. Remember to always close the file when you're done with it to release the resources.","dateModified":"2024-04-23T01:15:12.002Z"},{"@type":"Comment","author":{"@type":"Person","name":"Deleted User","url":"https://discord.com/users/456226577798135808","image":"https://cdn.discordapp.com/embed/avatars/3.png"},"datePublished":"2024-04-23T01:17:55.791Z","text":"^^^\nyou can just name the written file file.bin"},{"@type":"Comment","author":{"@type":"Person","name":"᲼","url":"https://discord.com/users/1208715763414728766","image":"https://cdn.discordapp.com/embed/avatars/5.png"},"datePublished":"2024-04-28T02:54:15.376Z","text":"true"}]}
