When Implicit Conversions Occur
The compiler automatically converts operands in the following circumstances:
• In most expressions, values of integral types smaller than int are first promoted to an appropriate larger integral type.
• In conditions, nonbool expressions are converted to bool.
• In initializations, the initializer is converted to the type of the variable; in assignments, the right-hand operand is converted to the type of the left-hand.
• In arithmetic and relational expressions with operands of mixed types, the types are converted to a common type.
• As we’ll see in Chapter 6, conversions also happen during function calls.
