yeah, i know. i wrote sth to print all the chars below space, but no luck in null, which is a non-printable, like \n or \t or others.

Allowed functions : write
• Create a function that displays a string of characters onscreen. If this string contains characters that aren’t printable, they’ll have to be displayed in the shape of
hexadecimals (lowercase), preceeded by a "backslash".
• For example :
Coucou\ntu vas bien ?
• The function should display :
Coucou\0atu vas bien ?
• Here’s how it should be prototyped :
void ft_putstr_non_printable(char *str);

Yeah, it's the only way. Thanks a lot man.

All you said is correct and I know it, but as I said, it's in a question. It asks us to print those control characters.

Yeah, exactly but I have no idea how to fix it. Even sizeof doesn't work because first one refers to array but second one to pointer.

I want to print non-printable chars in the middle of string. It's in a question I'm solving right now.

int main()
{
char str[] = "Coucou\rtu vas bien ?";
str[6] = 0;
printf("%zu\n", sizeof(str));
ft_putstr_non_printable(str);
write (1, "\n", 1);
}

void ft_putstr_non_printable(char *str)
{
int i;
// int len;
char *chars;

i = 0;
chars = "0123456789abcdef";
// len = ft_strlen(str);
printf("%zu\n", sizeof(str));
while (str[i] != '\0')
{
if (str[i] >= 32 && str[i] <= 126)
write (1, &str[i], 1);
else
calcs(str[i], chars);
i++;
}
}

void calcs(char c, char *chars)
{
char i;
char j;

i = chars[c / 16];
j = chars[c % 16];
write (1, "\\", 1);
write (1, &i, 1);
write (1, &j, 1);
}

great, thanks

Yeah, now I understood that 👍😉😄
Thanks man for your answer 👌

Yeah, it works and shows the number. I thought that would be harder and trickier.

Navid Rigi Ebrahimi 12-Jan-23 14:35pm View

It works and shows the result but I wasn't sure about it. I didn't think that to be so easy.
