switch speech, music, environment

Please help. I am doing a speech, music, environment classification. I want
to convert the code below into a 'switch' equivalent to used for multiple
if else 
        if pDSP<pDMU && pDSP<pDEN
            fprintf('%s  ', myFile(j).name)
            fprintf('- This is SPEECH\n') %label speech
        else if pDMU<pDEN
            fprintf('%s  ', myFile(j).name)
            fprintf('- This is MUSIC\n') %label music
            else
            fprintf('%s  ', myFile(j).name)
            fprintf('- This is Environment Sound\n') %label environment
            end
        end

If I had to guess, I'd say that you are asking about how to write C. 
There are better newsgroups for that, but I suggest book or an on-line 
tutorial. http://www.google.com/search?q=C+tutorial

The above code doesn't easily map to a switch statement. In C, the
case values that you put in a switch statement must be constant values
that are comparable (via the == operator) to the argument to the
switch. For example:

int i;
switch(i)
{
   case 0:
      // do stuff
      break;
   case 1:
      // do stuff
      break;
   // ...
}

Your case doesn't really call for a switch-case structure, if you ask
me. If you absolutely wanted to use a switch statement, you could
perform the comparisons ahead of time and set a flag indicating the
"type" of the audio (speech, music, or environment), then switch on
the flag values.
