string to byte array [closed]

I get very very long packets that are logged into a text file. But some I have to check for errors. example(a very short one):

I need an application that'd insert a ',0x' inbetween every byte so that later I can declare it as a static array.

The problem is that if I add this as a string, the compiler gives errors, because the string is too long. For this reason I'd be good if you could help me do this in one of the languages: C/C++,C# or Delphi.

You can use C# to convert your string to a byte array by using:

byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(yourString);

---

C#:

// get entire string
var contents = File.ReadAllText("filename.txt");
// convert every 2 digits 'AA' into ',0xAA'
contents = Regex.Replace(contents, "..", ",0x$0").Trim(',');
// output to another file
File.WriteAllText("filename2.txt");

---

In C:

#include <stdio.h>

int main(int argc, char* argv[])
{
    int ch;
    while ((ch = getc(stdin)) != EOF) {
        if (isprint(ch)) {
            if (! isspace(ch)) {
                printf("0x%c", ch);
            } else {
                printf("[0x%X]", ch);
            }
        }
    }
    return 0;
}

To invoke:

Windows:

type filename | program.exe

Unix:

cat filename | ./program

There is a distinction for spaces, tabs, newlines and carriage returns because you will inevitably encounter them in your efforts.
