Unlock the Power of File Handling in C Programming
Capturing User Input
When it comes to storing user data, file handling is an essential skill for any C programmer. In this example, we’ll explore how to create a program that takes a sentence entered by the user and stores it in a file.
The Code Breakdown
The program starts by storing the user’s input in a variable called sentence. This is where the magic begins.
Opening the File
Next, we open a file named program.txt in writing mode. If the file doesn’t exist, it will be created automatically. This is where the fopen() function comes into play, allowing us to interact with the file system.
Writing to the File
With the file open, we can now write the user’s input to it using the fprintf() function. This powerful function allows us to format and write data to the file. Once the data is written, we close the file to ensure that the changes are saved.
The Result
The end result is a program that seamlessly stores user input in a file, demonstrating the fundamental principles of file handling in C programming. By mastering this technique, you’ll be able to create more sophisticated programs that interact with the file system.
