              All statements that are parts of other statements must
              be compound statements
              (surrounded by braces).
              For example, the body of a loop
              must be a compound statement.  The parts of an if-statement
              must be compound statements.  For example,
if(x == 0) return 0; else return 2*x + 1;violates this rule. Use 
  if(x == 0) 
  {
    return 0;
  }
  else 
  {
    return 2*x + 1;
  }
              
              Compound statements must be correctly indented.  |
