R 7.9

Rewrite the following loops, using the enhanced for loop construct. Here, value is an array of floating-point numbers.

1. for ( int i = 0; i < values.length; i ++ ) { total = total + values[i]; }
2. for ( int i = 0; i < values.length; i ++ ) { total = total + values[i]; }
3. for ( int i = 0; i < values.length; i ++)
   {
       if ( values[i] == target ) { return i; }
   }

Is loop 2 supposed to be different from loop 1?
