Here is source code of the C Program to copy a file into another file. The C program is successfully compiled and run on a Linux system.
/*
* C Program to Copy a File into Another File
*/

include <stdio.h>

void main(int argc,char **argv)
{
FILE *fp1, *fp2;
char ch;
int pos;

if ((fp1 = fopen(argv[1],"r")) == NULL)    
{    
    printf("\nFile cannot be opened");
    return;
}
else     
{
    printf("\nFile opened for copy...\n ");    
}
fp2 = fopen(argv[2], "w");  
fseek(fp1, 0L, SEEK_END); // file pointer at end of file
pos = ftell(fp1);
fseek(fp1, 0L, SEEK_SET); // file pointer set at start
while (pos--)
{
    ch = fgetc(fp1);  // copying file character by character
    fputc(ch, fp2);
}    
fcloseall();    

}

Is there a way to append a list of files as an executable to the file itself such that the file is still executable?

For example let's say I have 2 files file1 and file2. How might I append the the files in a way to the binary. Again this is a simple example, I would like to have a cross Operating System way to extract Unix and Windows functions. Cross operating system way to append zips (or tar.gz) to a file only to extract it later.

The following illustrates how the files might be extracted and or created.

create ./a.exe ./output.exe file1 file2

extract output.exe
