file io - C style regarding fprintf -

-

if program has many lines of code print string file, of following preferred? how important use preferred format?

fprintf(file, "%s", "string file"); fprintf(file, "string file"); 

fprintf(file, "%s", "string file"); fprintf(file, "string file");

if string printed variable in way former version preferred one, if strings constants, hard coded, save use latter.

the danger using latter version variable strings evil mind enter conversion specifiers (%d, %s, ...) string make code pull stack not meant pulled. leads mayor security issues.
