Can I ask why you are using the system call from C to write to a file in the first place? You do realize that there exists a slew of API calls that are much more efficient than creating a new process to write a single line of text to a file.
Code:
FILE *fp;
fp = fopen("a.xml", "wt");
fprintf(fp, "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
fclose(fp);

you were having a mismatch of single quotes. I am able to write a.xml by following call.
system("echo '<?xml version=\"1.0\" encoding=\"UTF-8\"?>' > a.xml;");
