Sequential Access Files: Understanding feof() Function

What is the function used to determine whether an entire sequential access file has been read?

Choose the correct option:

a. fopen()
b. fread()
c. feof()
d. fclose()

Answer:

The function used to determine whether an entire sequential access file has been read is called feof().

The feof() function is essential when working with sequential access files in programming. It helps in detecting the end of the file, allowing developers to know when the entire content of the file has been processed. When feof() returns a non-zero value, it indicates that the end of file (EOF) has been reached, meaning that all data in the file has been read.

In languages like C and C++, feof() is commonly used in conjunction with file handling functions to efficiently manage file operations. By understanding how feof() works, programmers can ensure accurate file processing and prevent any issues related to incomplete reading of files.

It is crucial to grasp the concept of feof() and its application in handling sequential access files to enhance programming skills and streamline file processing tasks. Familiarize yourself with feof() and its significance in ensuring efficient file reading operations.
