In computer science, accessing files is an essential operation that allows us to store and retrieve data from a computer's storage system. There are two ways to access files in C - random access and sequential access. In this answer, we will differentiate between the two types of file access and discuss the role and syntax of fseek() and rewind() functions.

Random Access:
Random access refers to the capability to access any record or data element in a file directly, without the need to read through all preceding records. It means that we can access the contents of a file in any order. Random access files are suitable for applications that require frequent access to specific data elements or when we need to modify the contents of a file.

To use random access files in C, we need to declare a file pointer variable and open the file in "rb+" mode. The "rb+" mode is used ____________ _______ _____ ____________ ____ __ ____ ____ _____ ___ _____ _________ ___________ ___ ________.
