Question

______ is an alphanumeric value that is given within double quotes.​

Answer 1

Explanation:

The double quotation mark is identical to the ditto mark in English-language usage. It is also similar to—and often used to represent—the double prime symbol. However, the quotation marks, the apostrophe, and the prime serve quite different purposes.

In C and C++ the single quote is used to identify the single character, and double quotes are used for string literals. A string literal “x” is a string, it is containing character 'x' and a null terminator '\0'. So “x” is two-character array in this case. In C++ the size of the character literal is char.

A string constant or a string literal is a sequence of charecters enclosed by a pair of double quotes.
