Question

The if family of statements is used most effectively when the input is a scalar. Create a function to determine test grades based on the score and assuming a single input into the function. The grades should be based on the following criteria: Grade Score A B 90 to 100 80 to 90 70 to 80 60 to 70 с D E <60 Run your code for the following scores: 90, 75, 60 and 0.

Answer 1

function g=grade(num)
if num>=90 && num<=100
g='A';
elseif num>=80
g='B';
elseif num>=70
g='C';
elseif num>=60
g='D';
elseif num<60
g='E';
end
end

%save above code as grade.m and blelow code run in command window

grade(90)
grade(75)
grade(60)
grade(0)

octave: 6> function g=grade (num) if num>=90 && num<=100 g='A'; elseif num>=80 g='B'; elseif num>=70 g='C'; elseif num>=60 g='D'; elseif num<60 g='E'; end end grade (90) grade (75) grade (60) grade (0) ans = A ans = ans = D ans = E
