Class1. Types not defined in any namespace are said to reside in the global namespace. The global namespace also includes toplevel namespaces, such as Outer in our example.
An escape sequence is a backslash followed by a character with a special meaning. For example: char newLine = '\n'; char backSlash = '\\'; The escape sequence characters are: Char Meaning Value \' Single quote 0x0027 \" Double quote 0x0022 \\ Backslash 0x005C \0 Null 0x0000 \a Alert 0x0007 \b Backspace 0x0008 \f Form feed 0x000C \n New line 0x000A \r Carriage return 0x000D \t Horizontal tab 0x0009 \v Vertical tab 0x000B The \u (or \x) escape sequence lets you specify any Unicode character via its four-digit hexadecimal code: char copyrightSymbol = '\u00A9'; char omegaSymbol = '\u03A9'; char newLine = '\u000A'; Strings and Characters | 29 An implicit conversion from a char to a numeric type works for the numeric types that can accommodate an unsigned short.
Precedence The expression 1 + 2 * 3 is evaluated as 1 + (2 * 3) because * has a higher precedence than +. Left-associative operators Binary operators (except for assignment, lambda, and null coalescing operators) are left-associative; in other words, they are evaluated from left to right. For example, the expression 8/4/2 is evaluated as (8/4)/2 due to left associativity. Of course, you can insert your own parentheses to change evaluation order. Right-associative operators The assignment and lambda operators, null coalescing operator, and (ternary) conditional operator are right-associative; in other words, they are evaluated from right to left.
