WebC++ follows the OOPs concept which allows representing the string as an object of the C++ String class (std:: string). The class allows us to declare a string variable quickly, and store any sequence of characters in it. The following example shows the use of string with the help of the String class:
WebA single Char object usually represents a single code point; that is, the numeric value of the Char equals the code point. For example, the code point for the character "a" is U+0061. However, a code point might require more than one encoded element (more than one Char object). The Unicode standard defines two types of characters that correspond to …
