What does '\xB2' this mean in c++ ??

Question

Actually, I'm encounter this in someone's project

Answer 1

\x will render character that represent its hexadecimal form.

for example A has 65 as the character code, and 65 in hexadecimal is 41. so you can use \x41 as A.

in this case \xB2 is ²

Answer 2

each character has its own numeric code/form for computer to be able understand it.

we can use this numeric code to represent certain character that we probably cant type by our own, such as ² (exponent 2/superscript 2)

Answer 3

Answer 4

Taste but what xb2 is doing in that case

Answer 5

if you print \xB2 it'll render ² in the output
