Branching Constructs Why would IF be considered a branch? Lets look at what happens to our code when it is executing on the CPU Switch construct switch (switch_expression) case case_expr_1 statement 1 statement 2 case case_expr_2 statement 1 statement 2 otherwise statement 1 statement 2 end Switch construct color = yellow; switch (color) case red disp(Stop now!); case green disp(Proceed through intersection.); case yellow disp(Prepare to stop.); otherwise disp(Illegal color encountered.); end For loop for sum integers total = 0; for i = 1:1:100 loop starts at 1 total = total+i; loop increments by 1 end While loop while expression statement end While loop for sum integers total = 0; i = 1; while i
