Answer:
The maximum value that are represented as unsigned n -bit binary integer is . The unsigned binary integer refers to the fixed point of the system that does not contain any fractional digits.
The unsigned binary integer contain module system with the power 2. The number of student table in the class is the best example of the unsigned integer. The numbers can be represented by using the binary notation and bits in the computer system.

Explanation:
#include <stdio.h>
#include <sys/stat.h>
#include <stdlib.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
extern int errno;
struct stat st;
int main(int argc, char **argv){
int num1 = atoi(argv[1]); // Getting num1 from user
int num2 = atoi(argv[2]); // Getting num2 from user
char *fileSource = argv[3];
char *fileTarget = argv[4];
int source_fd = open(fileSource, O_RDONLY); // opening the file in read only mode
int target_fd = open(fileTarget, O_WRONLY | O_CREAT); // opening the target file in Writeonly mode if file is not found it will create
char *ch = (char *) calloc(num2+num1, sizeof(char));
stat(fileSource, &st);
if(st.st_size < (num1 + num2)){
printf("File Size is smaller than the specified bytes\n");
read(source_fd, ch, st.st_size); // reading the file upto the end
write(target_fd, ch, st.st_size); // write to the file
write(target_fd, ch, st.st_size); // two times writing to the file
}else{
if(lseek(source_fd, (off_t)num1, SEEK_SET) < 0 ) // moving the cursor to after the specified bytes from the start
{
printf("Some Error occured while seeking the file");
return -1;
}
read(source_fd, ch, num2); // reading num2 bytes from the source
write(target_fd, ch, num2); // writing two times to the target
write(target_fd, ch, num2);
}
return 0;
