Make a diagonal displayed message using linux in c language.

the code I already have is here:

#include

#include

#include

#include

#include

#include

#define LINESIZE 16

//use one command line argument

int main(int argc, char *argv[]) {

if (argc != 2) {

printf("Usage: diagonal ");

return -1;

}

//create a file so that 16 rows of empty will appear with od -c command

int fd = open("diagonal.out", O_CREAT | O_WRONLY | O_TRUNC, S_IRUSR | S_IWUSR);

char space = ' ';

for(int line=0; line;>

for(int column=0; column;>

write(fd, &space, 1);

//Each line of od outputs 16 characters

//So, to make the output diagonal, we will use 0, 17, 34, ....

int n = strlen(argv[1]);

for(int i=0; i;>

lseek(fd, (LINESIZE+1)*i, SEEK_SET);

write(fd, &argv[1][i], 1);

}

close(fd);

puts("diagonal.out has been created. Use od -c diagonal.out to see the contents.");

}

The output should be similar to this

The command line you'll need are:

gcc diagonal2.c -o diagonal2
