In this program we will read a String and convert the string to Hexadecimal String. The prefix “0x” is used in C and related languages, where this value might be denoted as 0x2AF3.For example, a single byte can have values ranging from 00000000 to 11111111 in binary form, but this may be more conveniently represented as 00 to FF in hexadecimal.Hexadecimal numerals are widely used by computer system designers and programmers. One hexadecimal digit represents a nibble (4 bits), which is half of an octet or byte (8 bits).It uses sixteen distinct symbols, most often the symbols 0– 9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a, b, c, d, e, f) to represent values ten to fifteen. In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16.
