Processing: Use a switch statement to perform the appropriate arithmetic operation based on the entered operator (*, +, -, 7). • Output: Display the result of the arithmetic operation to the user. What to do: 1. Prompt the user to enter an arithmetic expression as x operator y. Use cin >> x >> op >> y; to capture these inputs. 2. Employ a switch statement to determine the appropriate arithmetic operation to perform based on the entered operator. 3. Display the calculated result to the user. Criteria: • Use cin >> x >> op >> y; to capture user input. • Your code must utilize a switch statement for decision-making. • Only the operators *, +, -, / should be accepted. • You must use appropriate variable types and maintain a clear code structure. Code should be well-documented. C:…
