Question 1 In this exercise you will write a circular queue data structure (see Wikipedia: Circular buffer). You will also need two pointers: a head and a tail pointer. If there is still space in the queue, move the tail pointer and place the number into the associated array index. Following example makes use of three integers which will be stored in an array of pointers as follows In this article, we will take a look at the Array of Pointers in C and its uses according to the GATE Syllabus for CSE (Computer Science Engineering).
