/***************************************************
    Exercise 1.3
    Rewrite the following program using optimal C coding style.
    Pay attention to:
    - white spaces and indentation
    - short-cut boolean expressions in if or loop statements
    - use the conditional operator
    - code redundancy
    - proper use of the relational expression in a return statement
    - use of the comma operator in a loop
    - use of && and || to prevent if nesting
