Print "A" presented in HEX (printf("\0x41"))

Question

How to make `printf("\0x41")`; to rint 'A' letter. I know, that `\0` means end of line, but how to deal when I need to print character presented in `HEX`?

Accepted Answer

Drop the leading 0 in the hexadecimal character literal:

```
printf("\x41");
```

Integer literals use `0x` prefix, characters use `\x`.

You might also want to add a linefeed to make sure it appears:

```
printf("\x41
");
```

You can of course also print a single character:

```
printf("%c
", 0x41);
```

or portably:

```
printf("%c
", 'a');
```

Print "A" presented in HEX (printf("\0x41"))
