+* File: CST116-Ch6-Debugging.cpp
+*
+* General Instructions: Complete each step before proceeding to the
+* next.
+*
+* Debugging Exercise 1
+*
+* 1) On the lines indicated in the code below, insert a breakpoint.
+* 2) Run to the breakpoint.
+* 3) Put watches on both Fahrenheit and Celsius.
+* 4) When asked for a temperature, enter 212.
+* 5) Verify that the value you entered is stored correctly.
+* 6) Step over the conversion calculation. What is the value
+*    in Celsius? Is that the correct value? No.
+* 7) Remember your order of precedence. Put parentheses around
+*    Fahrenheit - 32. This needs to be done before the multiplication.
+* 8) Stop debugging and recompile.
+*
+* Debugging Exercise 2
+*
+* 1) Run to Breakpoint 1.
+* 2) When asked for a temperature, enter 212.
+* 3) Verify that the value you entered is stored correctly.
+* 4) Step over the conversion calculation. What is the value
+*    in Celsius? Is that the correct value? No.
+* 5) Look at the division. This is integer division. Therefore,
+*    5 / 9 = 0. This is not the result we are looking for.
+* 6) Modify the calculation so that it does floating point division.
+*    There are three different ways we have discussed:
+*           a) use the F suffix on the literals
+*           b) type cast the literals
+*           c) replace the 5 with 5.0 and the 9 with 9.0
+* 7) Stop debugging, recompile and run to verify that it now works
+*    correctly.
