clc;clear
C1 = input("Please enter a code to break: " , "s");
if length(C1) ~= 6
disp("Decoy message: Not a six-digit number.");
else
A = sum(C1 - '0');
if
mod(A , 2) = 1;
disp("Decoy message:Sum is odd.");
else
C2 = (C1(1) - '0') * (C1(2) - '0') - (C1(3) - '0');
switch C2
case 1
disp("Monday")
case 2
disp("Tuesday")
case 3
disp("Wednesday")
case 4
disp("Thursday")
case 5
disp("Friday")
case 6
disp("Saturday")
case 7
disp("Sunday")
otherwise
disp("Decoy message:Invalid rescue day.");
end

if C2 == 1
disp('Monday');
elseif C2 == 2
disp('Tuesday');
else
disp('something else');
end

My homework does not let me to use if elseif for the part C2, only switch statement is allowed... Can you please show me how to do this with switch statement?

?? You already seem to be using switch(), so I am not clear as to what you want to do?
Perhaps you are looking for
if mod(A , 2) == 1;
disp("Decoy message:Sum is odd.");
elseif some condition
else
some more code for when the sum is odd but the switch does not apply
end
