My first switch statement

Former Member

Im trying to use a switch statement to jump to a different function.  All of the lessons I find just tell me how to turn on leds or outputs.  So I have no idea of what to do here.  So far I have this.

 

 

{

int range;     // I just used this cause it was in an example, I think I need it to name my switch statement. 

int flasha;  //  This is the subroutine I want to run.  I will have more late just trying to figure out the first one.

switch(range);

{

case 0:  //  I don't know why I have  to use "0"  it is just in all of the examples and nothing else works.

state==1, flasha;  // state is my input.  When a button is pressed it will count the number of presses and send it to the approiate subroutine.

break:

}

}

 

When I compile this program I get the error

 

case label '0' not within a switch staetment.

 

Can anyone explain what this means or what I'm doing wrong?

 

Thanks

    OK Guys I got it to work.  YEA!!!!!  The switch statement is working right and the counting is working just fine.  I made 3 different states and they loop around just like I want it to.  Thanks for all the help.  Anyone want to guess what I did?  Here it is.  I cookie for the first one to figure it out.  Now my next question is.  Can I put a switch statement inside a switch statement?  As it is now it will print both outputs.  The final version of the program will print one output at a time while remembering where the other output is at.  Also when 1 output gets to 3 both outputs will reset to case 0.

     

     

     

     

     

     

    int state=8;//set pin 8 as state

    int mi=9;  //set pin 9 as mi

    int lastState=LOW;  //
