PHP echo Hex Value
Echo 0x9f;?>
Run Program output 159.
159 of the 16 binary is 9f, why the front to add 0x?
And why is it possible to output a 16 binary value directly instead of an error?
Share to: 运行程序输出159。159的16进制是9f,为什么前面要加0x呢?还有这里为什么可以直接输出一个16进制数值而不是报错呢?" data-pics="">

Executable and linking format (ELF) files are commonly used object file formats in x86linux systems. There are three main types:
(1) a relocatable file suitable for connection. It can be used with other target files to create executable files and share the target files.
(2) executable file, used to provide
Program Process image, the loaded memory is executed.

Basic practice decimal to hexadecimal time limit: 1.0s memory limit: 512.0MBThe problem description hexadecimal number is a representation of an integer that is often used in programming. It has 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f a total of 16 symbols, representing 0 to 15 of the decimal number. The hexadecimal count method is 16 in 1, so the decimal number 16 in hexadecimal is 10, while the decimal 17 in hexadecimal is 11, and so on, the decimal 30 in hexadecimal is 1 E.A nonnegative integer is gi
