Here you can find the skeleton of a Java program which you can use for today's lab.
Stage 1:
Prompt for two integers (read as int).
Prompt for an operator (read as String, extract 1st character).
Set of if-else-if statements to do the correct operation.
Print output on the screen.
Stage 2:
Put the above in a loop to allow doing it more than once.
Stage 3 (Advanced):
Implement exponentiation, using '^' as the operator symbol.
