Recommended Program Layout Style

  int a;

  }

    if (a > 0) { // If statement
      return a + b; // Single statement
    } else if (a < 0) { // Nested if-else, block statement
      int res = -a + b;
      return res * 117;
    } else { // a == 0 // Terminal else, block statement
      int sum = 0;
      for (int i = 0; i < 10; i++) { // For loop
        ;
      }
      return sum;
