How to convert an unsigned char to a string?

Question

I'm needing to collect byte by byte of an unsigned char and convert it to a string, how can I do that?

I've tried everything but it didn't work.

My example code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
    unsigned char byte_loop[10] = {0xa0, 0xb1, 0xc2, 0xb3, 0xd4, 0xe5, 0xa6, 0xb7, 0xc8, 0xa9};
    char text_concat[11];

    for (int i = 0; i <= 10; i++)
    {
        text_concat[i] = byte_loop[i];
    }

    printf("%s", text_concat);

    return 0;
}

Thanks

The code is essentially correct. The problem is the data that you chose to put in byte_loop[10]. It's pretty much all unprintable or invalid ASCII codes. Try using 0x61 through 0x6a (a through j) instead.

You'll probably want to add code to handle non-printable values or non-ASCII values, after consulting an ASCII table to see what's valid for your purposes.
