6.10.2. Components of Statements

Components of statements [Statement component: 1-5 points]

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.
