Question

Print Helloworld in C without using semicolon [Only Once]

#include<stdio.h>
void main()
{
   if(printf("Helloworld"))
   {
   }
}

Print Helloworld in C without using semicolon [infinite times]

#include<stdio.h>
void main()
{
   while(printf("Helloworld"))
   {
   }
}

On the above lines you can do it with switch or can define a macro which can be used in while/switch or if statement.
