		exit(0);
	}
	fs = fopen(argv[1],"r");
	if(fs==NULL) {
		puts("Source file cannot be opened.");
		exit(0);
	}
	ft = fopen(argv[2],"w");
	if (ft==NULL) {
		puts("Target file cannot be opened.");
		fclose(fs);
		exit(0);
	}
	while(1) {
		ch=fgetc(fs);
		if (ch==EOF)
		   break; else
		   fputc(ch,ft);
