Answer:
The solution code is written in Java.
- Scanner input = new Scanner(System.in);
- System.out.print("Enter operator: ");
- String operator = input.nextLine();
- System.out.print("Enter first integer: ");
- int num1 = input.nextInt();
- System.out.print("Enter second integer: ");
- int num2 = input.nextInt();
-
-
- int result = 0;
-
- switch(operator){
- case "+":
- result = num1 + num2;
- break;
- case "-":
- result = num1 - num2;
- break;
- case "*":
- result = num1 * num2;
- break;
- case "/":
- result = num1 / num2;
- break;
- default:
- System.out.println("Invalid operator");
-
- }
-
- System.out.println(result);
Explanation:
To ask for the user input for two whole numbers and an operator, we can use Java Scanner class object. Since the input operator is a string, we can use nextLine() method to get the operator string (Line 3). We use nextInt() method to get whole number input (Line 5 & 7).
Next we use the switch keyword and pass the operator into the switch structure to determine which case statement should be executed. For example, if the input operator is "*" the statement "<em>result = num1 * num2;</em>
" will run and multiply <em>num1</em> with <em>num2. </em>
