Why is code tracing important when debugging?
larisa [96]

It helps reveal the flow of execution of your program, including results of in-between evaluations. In other words, you can see what your program is doing, and why it takes the decisions it is taking.

If something unexpected happens, the trace will show you the sequence of events that lead to it.

Why might a variable used for output have to be of a different type then a variable used for input?​
telo118 [61]

Answer:

You may use a different variable type for input in order to process the data appropriately and may use a different variable type to accommodate your program.

Explanation:

Your input may have to be different then output varying on what data you are processing.

For example, just like the last question you asked about calculating the area of the rectangle, your input MUST be converted to a different a numerical data type (i.e int or float) in order to do the math.

Based on your last question, if we didn't convert your input into a string your results wouldn't add the numbers together but only concatenate them. If I typed 3 & 5 as length & width, I would get 35 instead of 15.

Now another example is using functions (or methods whatever you want to call them), your input can be one thing and outputs another.

Let's say I want a function to tell me if I am smart. The way I want it to determine if its smart is by inputting my GPA into it, which is a numerical value. So the function would look something like this:

<u>Code (Python)</u>

def IsSmart(gpa):

  if (gpa >= 4):

       return True

  else

       return False

As you can see I am inputting a numerical value and it is outputting a boolean value. I can use this in a if else chain to spit out an output to the user.
