## What is 0xf9?

ASCII/Binary of 0xf9: ù The most popular extension is Windows-1252, with is shown here. This page shows all the information about 0xf9, with is the character ‘ù’ including the HTML code, the key combination and the hexadecimal, octal and birary encoding of the value.

### What is 0b and 0x?

0b (or 0B ) denotes a binary literal. C++ has allowed it since C++14. (It’s not part of the C standard yet although some compilers allow it as an extension.) 0x (or 0X ) is for hexadecimal. 0 can be used to denote an octal literal.

#### What does 0b1 mean in binary?

0b1 = 1 in binary = 1 in base‑10. 0b10 = 10 in binary = 2 in base‑10.

What is 0b C++?

Binary literals are a feature supported in many programming languages such as Java, D and Python as well as a compiler extension in C++ and C. Binary literals typically start with 0b or 0B followed by a series of binary digits.

What does 0b mean in C?

binary literal
0b (or 0B ) denotes a binary literal. C++ has allowed it since C++14. (It’s not part of the C standard yet although some compilers allow it as an extension.) 0x (or 0X ) is for hexadecimal. 0 can be used to denote an octal literal.

## What is a uint16_t?

uint16_t is unsigned 16-bit integer. unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it’s at least 16-bit (i.e, minimum value of UINT_MAX is 65535 ). In practice, it usually is 16-bit, but you can’t take that as guaranteed.

### Should I use uint16_t?

Use the plain types ( int etc) except when you need a precisely-sized type. You might need the precisely sized type if you are working with a wire protocol which defines that the size field shall be a 2-byte unsigned integer (hence uint16_t ), but for most work, most of the time, use the plain types.

#### What is int8_t?

Thus, int8_t denotes a signed integer type with a width of exactly 8 bits.

Is uint16 short?
