A circular buffer is an array of constant length, and we use it to store data in a continuous loop. It is also known as a ring buffer because it stores the data circularly. Data is read from the buffer in a FIFO (first in, first out) manner, meaning that the oldest data is read first.We use the buffer to store and transfer … See more In this tutorial, we’ll learn the concept of a circular buffer in engineering and computer science.
