/********************************************************************
* Andrei Florea - CST 116 - Ch6 - Debugging
* 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.
*
* Using the debug watch variable, fahrenheit has a float value of 212
*
* 6) Step over the conversion calculation. What is the value
* in Celsius? Is that the correct value? No.
*
* The value in Celsius is 0 on the watch for the variables
*
* 7) Remember your order of precedence. Put parentheses around
* Fahrenheit - 32. This needs to be done before the multiplication.
*
* Done, the parentheses are now around the Fahrenheit - 32, however,
* celsius is still equal to 0, which I think is because of the 5 / 9 (integers) that
* result into a 0.
*
* 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.
