 		 #162252 - Local variables within inner blocks
Responding to: ???'s previous message
Kiran V. Sutar said:
2. You have defined parameters inside the function and after using the commands...remember Keil is C ..NOT C++. So define them at the begining of th function..example of your mistake:


Note that 'C' does permit you to define variables within inner blocks; eg,

Save This Code
void function( void )
{
   int loop_words; // this variable is local to the function

   for( loop_words=0; loop_words<3; loop_words++ )
   {
      int local_var; // this variable is local to the block formed by the 'for' 
   }
}

 

In principle this might be advantageous in giving the compiler more scope for overlaying; in practice, I don't think Keil C51 takes advantage of this.
