The function that allows you to write formatted output to a file is widely recognized as fprintf. This function operates similarly to printf but directs the formatted data to a specified file rather than the console.

When you invoke fprintf, you can include a format specifier along with the necessary arguments, which provides flexibility in defining how the data is presented in the output file. For instance, you can format numbers, strings, and other types seamlessly, making it ideal for situations where precise output formatting is critical for readability or compliance with other systems.

In practice, to use fprintf effectively, you first need to open a file (typically using fopen), and then pass the file pointer along with the desired format string and additional data to fprintf. This capability makes fprintf a powerful tool for any programming tasks that involve logging, reporting, or data export where the format is important.
