A character constant is a single character in the host's character set, such as 'A', 'a', '0', '%', etc. Note the use of the single quotes instead of double quotes. (Double quotes are used for string constants, not character constants.) A character constant maps to a specific int (integer) value, but assuming anything about that relationship is non-portable.
Integer constants Character constants Real/floating point constants String constants

A default character is the kind d type for characters constants if no kind parameter is specified.
character constant is 4 bytes explanation is all constants is integer
In Scilab, predefined numerical constants are typically defined using the % character. For example, %pi represents the mathematical constant π (pi), and %e represents Euler's number (e). These constants are built into Scilab and can be used directly in calculations without needing to define them explicitly.
A character type constant is a character, a char, while a string type is an array of characters. The character type constant is one character and is delimited by single quotes. The string type constant is zero or more characters and is delimited by double quotes.
There are 4 constants.
Variables change, constants do not.
Coding constants in c means writing the constants in a certain way that the c language understands.
Constant in C means the content whose value does not change at the time of execution of a program.There are several types of constants $ they are i>numeric->a.INTEGER b.REALii>character->a.SINGLE CHARACTER b.STRING.Hope this will help you.
It's arbitrary. That's the way that constants are defined.
C++ Provides a multiple branch selection called as switch. This selection statement succesively test against a list of integer or character constants. When a match is found the statements associate with constants are executed. When no match is found default statement is used.
