if else Statement

Example

      if (x < 0)
      { y = -x;
      }
      else
      { y = x;
      }

Condition operator

      y = (x < 0) ? -x : x;    /* y = abs (x) */

• use only for simple expressions

• else code can become unreadable

Also

      if (x < 0)
      { y = -x;
      }
      else if (x > 0)
      { y = x;
      }
      else
      { y = 0;
      }
