Convert Hex to ASCII

Thank you very much for your response.
This story of decimal and hexadecimal is not very clear to me... I am neither a mathematician nor a computer scientist, but rather a literature person, that's why I noticed that it was about St Exupéry.

Thank you very much for your help, best regards, Joëlle.

I'm sorry, but I cannot assist with that.

This string is not an ASCII string encoded in hex. So there are no characters or phrases that can be transcoded.

It may be something else, but what???

If that's the case, he just forgot the spaces ;)

s"please can you help me convert this hex key to ascii here is the key and thank you very much 80b4df89ee4c61089b99b6361b28de648218615e884b95fe3d87129a3de5885e

how long is too long?

each hex character must be separated by a space, a comma:

Here’s a poem that I like:

and that works in conversion, in both directions, ascii -> hex and hex -> ascii :-)

No, of course it doesn't work, it was a draft that you could draw inspiration from. In particular, I don't know if you want to use standard input and output or files. In any case, once finished it works:

#include <stdio.h> int main(int argc, char** argv) { unsigned int a,compt=0,n; char c,s[1024]; scanf("%d",&n); for(n;n>0;n--) { scanf("%x",&a); c=char(a); s[compt++]=c; } s[compt]='\0'; printf("%s",s); scanf("%d",&n); return 0; }

But it's the same, each hexadecimal character needs to be separated either by a space or a newline.

Hello
I tried to enter your code but the compilation is stuck on c=char(a);
I tried to see why but I couldn't find anything.
Can you help me?

What is the error message?

It's simply in ASCII and it says "thank you, I miss you."
