Output
Case 1:
Enter the first number: 5
Enter operation (+, -, *, x, /): +
Enter the second number: 7
5.0 + 7.0 = 12.0
Case 2:
Enter the first number: 10
Enter operation (+, -, *, x, /): x
Enter the second number: 3
10.0 x 3.0 = 30.0
Case 3:
Enter the first number: 8
Enter operation (+, -, *, x, /): /
Enter the second number: 2
8.0 / 2.0 = 4.0
