When doPlot is 0, did you not plot the data?

Modify the script so that the plotting code on lines 5–8 execute only if doPlot is 1

That might be checking that the densities that are printed as text when doPlot is 0 exactly match the densities that would be printed by "the code as shown above". The code you're using doesn't exactly match: note that your code doesn't display a space between "of" and the name of the element. Try adding the spacing before and after the element name (as I believe "the code as shown above" does) and see if that allows you to pass the test case.

Compare:
x = 1;
y = 2;
disp("The value of x is" + x + "and the value of y is" + y)
disp("The value of x is " + x + " and the value of y is " + y)
The two phrases displayed are not identical. If your code displayed the first of those phrases but the exercise expected the second your code would not pass the test.

Hi Steve
Thanks for the quick response.
Even after following the phrase is still saying incorrect.
thanks.

You'll be laughing, but you need just put spaces inside the phrases "The density of the" and "is" so that they look like "The density of the " (a space after the whole phrase) and " is " (spaces before and after the word).

load datafile
density = data(:,1);
if doPlot == 1
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
end

Comparing to 1 is not necessary in the case where the values are guaranteed to be either 0 or 1.
In the case where the values are not guaranteed to be one of those two, then you need to know whether the rule is that the number must be exactly 1 to pass, or if the rule is that the number must not be zero to pass.

if doPlot
plot(density)
title("Sample Densities")
xticklabels(element)
ylabel("Density (g/cm^3)")
else
disp("The density of" + element + "is" + density)
end

name = "Bongani Tavengwa";
disp("Do you see the problem now" + name)
disp("Do you see the problem now " + name)
Do you see the difference in the two displayed statements? What's the difference between the second and third lines of code and what impact does that difference have in the displayed text?

if doPlot
plot(density)
title("Sample Densities")

ylabel("Density (g/cm^3)")
else
disp(" The density of " + element + " is " + density)
end

The problem is solved only when you give gaps between words in the bracket. Notice the spacing i gave. It worked
disp(" The density of " + element + " is " + density)

If you have the same problem, then Walter already gave the answer. If you have a different problem, nobody can possibly know what it is unless you describe it.
