Chapter 10: File Handling

 File handling is crucial for reading from and writing to files in C programming. In this chapter, we'll dive into file handling and understand how to perform file operations using C. You'll learn how to open and close files, read and write data to files, and handle errors during file operations. We'll also cover topics like file positioning and working with binary files. Real-world examples will help you understand the practical applications of file handling in C.

Example:

#include <stdio.h> int main() { FILE* file; // Declare a file pointer // Open the file in write mode file = fopen("data.txt", "w"); // Write data to the file fprintf(file, "Hello, file handling!"); // Close the file fclose(file); return 0; }

Explanation:

We declare a file pointer variable called file. We use the fopen() function to open the file "data.txt" in write mode. Using the fprintf() function, we write the string "Hello, file handling!" to the file. We close the file using the fclose() function.

To compile and run the program, follow the same steps as in the previous chapters.

Congratulations! You've completed the 10 chapters of this C programming tutorial. Each chapter has provided you with in-depth explanations and practical examples to enhance your understanding of C programming concepts. You're now equipped with the knowledge to start building your own C programs and explore further in the world of programming.
