rewrite the following code segment containing an if-elseif using a switch-case structure instead of the if-elseif. The code should not contain any ifs and should employ minimum number of disp commands. assume a is always a positive number
if a<60
disp('f)
elseif a<70
disp('d')
else
disp('good job')
my attempt was a=input(' ') switch a case a<60 disp('f') case a>= 60 & a<70 disp('d') otherwise disp('edit you') end

Homework needs an honest attempt first -- post your work and a specific question...meanwhile, there's always
doc switch
with and example to get you kick-started...

Dear Mike, You can convert if-else code to switch case structure as follows:
InputValue = input('Input value: ');
val = sum(InputValue < [70 60]);
switch val
case 2
disp('f')
case 1
disp('d')
otherwise
disp('Good job')
end
I hope it helps. Good luck!

Can you generalize your answer for arbitrary conditions?
There is an obvious generalization by using several switch statements, but you did this with only one switch statement, but your answer somehow depends on the condition.
