/********************************************************************
* 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. The value is -32 which didn't seem right.
* 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. We got the answer to be 100 Degrees Celcius.

#include <iostream> This is the start of the iostream statement entering to the code
#include <iomanip> Here we have the start of the information for the code with the extra wording statements
using std::cout; Here we have the cout statement starting in the code
using std::cin; Here we have the different work to help out in the cin statements for the code
using std::endl; Here we have the start of the end line information for the code
int main() Here we have the information to start the main function in the code
{
float fahrenheit = 0; Here we have the fahrenheit float
float celcius = 0; Here we have the information for the celcius float
cout << "Enter temperature in Fahrenheit: "; Here we have the cout statement to enter the temperature in fahrenheit
cin >> fahrenheit; Here we get the entry for fahrenheit
// Breakpoint 1
// Put a breakpoint on the following line
celcius = 5.0 / 9.0 * (fahrenheit - 32.0); I put a breakpoint in here and then we have the calculation for the celcius float
cout << fahrenheit << " degrees F = " Here output the fahrenheit float and the amount of the degrees statement
<< celcius << " degrees C" << endl; Here we have the information to output the Degree of celcius and put the statement of the Celcius in the function.
return 0;
