Question

7. Celsius Temperature Table The formula for converting a temperature from Fahrenheit to Celsius is the Fahrenheit temperature and C is the Celsius temperature. Write a func- he func- tion named celsius that accepts a Fahrenheit temperature as an argument. I tion should return the temperature, converted to Celsius. Demonstrate t he function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their Celsius equivalents.

Answer 1

Since it is not mentioned in which language the program needs to be implemented, MATLAB is selected to develop the code.

MATLAB Code

%initializing the vector of Fahrenheit
fh=0:20;
%Display the heading on the command window
fprintf('Fahrenheit\tCelsius\n')
%'for' loop calling 'celsius' function
for m=1:length(fh)
%Calling 'celsius' function
cg=celsius(fh(1,m));
%Display fahrenheit and celsius temperature on command window.
fprintf('%1.2f\t\t%1.2f\n',fh(m),cg)
end
%function definition
function c=celsius(f)
c=5/9*(f-32);
end

Output on the command window
