'b' is a character literal. A character literal is a character enveloped in single quotes, just as a String literal is a String enveloped in double quotes (without the use of a constructor.)
Well, A is an identifier; 'A' is a character-literal; "A" is a string literal (of 1 character); "'A'" is another string literal (of 3 characters).
char c = 'a'; 'a' is a literal character, which assigns the value 0x61 (ASCII code 97 decimal) to the char variable c. The following lines are therefore equivalent: char a = 0x61; char b = 97; char c = 'a';
example: SELECT name, '*', address FROM table; Here '*' is a literal character.
a -- identifier 'a' -- character-literal "a" -- string-literal
Character array (string literal).
A literal can be a number, a character, or a string. For example, in the expression, x = 3 x is a variable, and 3 is a literal.
In Java, a literal is the source code representation of a fixed value and are represented without requiring computation. The various types are Integer, Floating-Point, Character and String literals.
Literals are either numeric types (integers and floating point types), or character types. int i = 42; // literal integer double pi = 3.14; // literal floating point char c = 'x'; // literal character char s[] = "Hello world"; // literal string Note that you cannot take the address of a literal since there's no way to refer to it.
An algebraic identity like (a+b)(a-b)=a2-b2
A group of character data, in SQL, is known as: Literal Values. This includes characters, numbers, or dates. Some prime examples of literal values are: dollars has a monthly salary of: January 1, 2009
In C programming, string literals are specified using double quotes ("). For example, "Hello, World!" is a string literal that starts and ends with double quotes. Character literals, on the other hand, are specified using single quotes ('), such as 'A' for a character literal.
Characters are simply character codes, so they can be compared just like any other value. They can also be compared using literal character constants. The compiler will replace character literals with their equivalent character codes. char c = 'a'; // variable c is 0x61 (hex) or 97 (decimal). if( c 97 ){...} // true, 'a' is character code 97 decimal. if( c > 'b' ){...} // false, 'a' is not greater than 'b' (that is, 97 is not greater than 98).
