COMP1210 - Lecture Notes 4 File Processing File processing in C++ involves operations such as reading from and writing to files. C++ provides a rich set of libraries for file handling, allowing both sequential and random access to files. File Handling Basics C++ uses fstream library for file operations, which includes three main classes: a. ifstream for reading files. b. ofstream for writing files. c. fstream for both reading and writing. Opening and Closing Files To open a file, you can use the open() function or the constructor of the file stream object. It's crucial to close the file after operations using the close() method. #include #include using namespace std; int main() { ofstream outfile("example.txt"); // Open for writing if (outfile.is_open()) { outfile
