1. Create a program that will arrange the values of A,B,C and D in highest to lowest order where variable A gets the highest value and variable D gets the lowest value. The values of the variables are: A=3, B=9, C=12 and D=6.
2. Swap the data variables A and B, C and D, and E and F; where A=20, B=25, C=30, E=40 and F=45
