circular array

To create a circular array in C++, you can follow these steps:

1. Declare an array of a specific data type and specify its size.
2. Declare two variables, "front" and "rear," to keep track of the front and rear indices of the circular array, respectively. Initialize both variables to 0.
3. Implement the "enqueue" function to insert an element into the circular array: a. Check if the circular array is full by comparing the value of "rear" with the size of the array. If they are equal, the array is full. b. If the array is full, display an error message and exit the function. c. If the array is not full, insert the element at the "rear" index, and increment "rear" by 1. d. If "rear" becomes equal to the size of the array, set "rear" to 0 to wrap around the circular array.
4. Implement the "dequeue" function to remove an element from the circular array: a. Check if the circular array is empty by comparing the value of "front" with the value of "rear". If they are equal, the array is empty. b. If the array is empty, display an error message and exit the function. c. If the array is not empty, remove the element at the "front" index, and increment "front" by 1. d. If "front" becomes equal to the size of the array, set "front" to 0 to wrap around the circular array.
5. Implement the "display" function to print the elements of the circular array: a. Start a loop from the "front" index and iterate until reaching the "rear" index. b. Print the element at each index.
6. Test the circular array implementation by calling the necessary functions and checking their outputs.

Note: It is important to handle the cases where the circular array is empty or full to avoid any errors or unexpected behavior.
