%[flag][width][.precision][modifier]<type>

meaning of fields with e.g.,:
format                                                                        output
1. flag: printf(“%7s”,”hello”);                                 spacespacehello

2. width: prinf(“%4d”,10);                                         spacespace10

3. precision: (“%.2f”,1.1412);                                                  1.41

4. modifier:

h interpreted as short used with  i,d,o,u,x
l interpreted as long used with i,d,o,u,x
L interpreted as double used with i,d,o,u,x

5. type: d,i,x,X as their usual meanings etc.
