Declaring a hex value in C++ is straightforward and can be done using a prefix or converting decimal values. Hexadecimal (hex) values are base-16 values, represented by digits from 0 to 9 and the letters A to F.<\/p>\n

To declare a hex value, simply prefix the value with either “0x” or “0X”. The prefix signals to the compiler that the value following it is in base-16 (hexadecimal). Here is an example:<\/p>\n

“`cpp
\nint hexValue = 0x7B;
\n“`<\/p>\n

In the above example, the variable `hexValue` is declared with a hex value of 7B, which is equal to 123 in decimal.<\/p>\n
