hi miss matika. strncmp() is the easiet way for comparing strings and it helps in arranging.
for example if you want to arrange accoring to the first letter
strncmp(st1,st2,1) // 1 is the number of letters you are going arrange according to it.
1- the function returns 0 if the letters are the same
2- the function returns -1 if the first letter of st1 smaller than st2
3- the function returns 1 if the first letter of st2 smaller than st1
The question is : Is there is a function which switch the places of two strings with each other.
you can also use this function... balas(); " It is very usefull trust me "
but u must include "radi.h"
thnx
bye :cheesy:

sorry

The answer is quite simple:
Just use "<"or">" operators in an "if" instruction like in a normal sorting method for numbers. Be careful though:
if you have:
s1[]="abcdef",s2[]="afsdg"; and you write
if (s1>s2) printf("1");
else printf("2"); it will write 2 as in s2 larger than s1 so s1 has to be first: abcdef, afsdg
Hope it helps! :cheesy:
