I have made a sample code in c.

do
{


 switch(i)
 {

 case 1:
 {
   cout<< "1\n";
   break;

 }
 case 2:
 {
      cout<< "1\n";
      break;
  }
  case 3:
  {
    continue;
  }


 }
 }while (0);

Here in this code if value of i is 3 then i want to restart the do while loop which will result in an infinite loop. But unfortunately loop is not getting executed again. What will be the reason for that.? I have checked the assembly code in visual studio of the same code and found that there is no JMP statement in the assembly for continue statement inside switch -case .

Answer 1

while (0) means it will fall out the bottom of the loop. Even if you have continue the condition is re-eval'd

Answer 2

When you do continue inside a do-while loop, it jumps at the evaluation at the bottom, that is always false in your case.

Answer 3

The other answers are explaining continue but it looks from your comments like you understand how that works.

if value of i is 3 then i want to restart the do while loop which will result in an infinite loop

The code is functioning as you describe - it is jumping to the 'while' condition on i==3. The only difference is that if you want an infinite loop you need while(1) not while(0).
