how to convert \x1 \x2 \x3 … characters to normal characters without erasing in c++

问题

Hi guys sorry for the noob question what are those \x1 ..\x2 ..\x3 characters and how to convert these to normal characters?

回答1:

They are characters with the ordinal values 1, 2, and 3. They are called control characters and are not printable, which is why the debugger is showing you their escaped representation.

You can look the control characters up in an ASCII table.
