 Thanx for ur immediate response , i really appreciate that .
 Is by [6.4]/3 ur mean is ISO standards 6.4 point 3 .
 I checked the ISO standards 6.4 point 3 . It is a saying that variable is in
 scope from its point of declaration until the end of substatements
 controlled by the condition .
 but in particular example
 if ( int i == 5)
 {
 }
 i = 9 ;
 here "i"  is not in scope of if statement . and also if u try to assign i to
 some other variable there it says error .
 
 int j ; if ( int i == 6) {}  j = i;
 
 i am in doubt regarding this ,
 plzz clarify it .
 
 thanx and regards
 ritesh

>Description:
gcc is allowing the usage of variable outside the scope of if stmt, if that variable is defined inside the condition expression of that if stmt and used as th first token after the scope of that if stmt .
as in eg.
void func()
{

   if ( int i = 9)
      {
        //
       }
    i = 8;
}

this should be an error but gcc is allowing 
i am using gcc3.0
