                               do
                                {
                                     printf("%d\n",sum);
                                     sum+=i*i;
                                }


                               while(i>3);
                               {
                               i=43;
                               i-=3;


                               if(i==23)
                               break;
                               }


                                return(0);
                           }
error  break statement not within loop or switch


could someone tell me what is the problem,plesase?

A little bit of formatting might help you see the error:

Code:

int main()
{
   int i,sum;

   do
   {
      printf("%d\n",sum);
      sum+=i*i;
   }while(i>3);

   {
      i=43;
      i-=3;


      if(i==23)
         break;
   }

   return(0);
}

Is the break statement inside a loop, or switch statement?


Jim

i m sorry, i fully dont understand the meaning of switch statement. Inside the loop.

It is not the switch statement that is not inside a loop. It is the break statement not inside a loop. A break must be either inside a loop or inside a switch statement. Is your break statement inside a loop? Inside a switch statement?

Jim

Inside a loop.

The problem is that the break statement is not inside a loop. Look at your code I re-posted, your break statement is not inside any loop.

Please see this link: Control Structures.

Jim

Is it? Where does your loop start (and how do you know?) and where does it end (and how do you know)? What would your loop look like, if it didn't do anything? Just the empty loop?

Ok... since nobody else has done this, so far...

Code:

int main()
{
   int i,sum;

   do
   {
      printf("%d\n",sum);                 <---- this is your loop
      sum+=i*i;
   }while(i>3); 


  {
      i=43;
      i-=3;                                    <---- this is not.

      if(i==23)
         break;
   }

   return(0);
}

Get it now?

If you want to know what a switch() statement is ... look it up!

yes.thank you.
