Problem 4. (20 Points)
Ask the user to enter two numbers. Store these in two variables and then swap the values before
displaying them
Sample program output:
Please enter two numbers:
10
20
Swapped values are 20 and 10
NOTE: DO NOT just print them in opposite order. The values have to be swapped in the variables used
to store them
For example if you stored the first number in a variable var1 and the second in var2 at the end of your
code the number which was originally in var1 should now be in var2 and the number which was
originally in var2 should now be in var1
