Hi,

If I have a string like
"ABC_DEF_123"

How would I seperate the three of them ?
what I want is the three of them seperated for example
after seperation :
temp1 will contain "ABC"
temp2 will contain "DEF"
and temp3 will contain "123"

How would I do this ? I tried using standard stuff but still
am unsuccessful ...

Any help will be appreciated.
Thanks

Use strtok inside a loop:

The first call is done outside the loop when the first param is the string you want to parse.
Then you just loop for as long it returns something, whith the first parameter set to NULL

Another option is to use scanf() with sets ([...] and [^...]).

#include <string.h>

char *string="ABC_DEF_123";
char *temp1,*temp2,*temp3;
temp1=strtok(string,"_");
temp2=strtok(0,"_");
temp3=strtok(0,"_");
printf("trmp1=%s, trmp2=%s, temp3=%s;\n",temp1,temp2,temp3);

/*Another option is to use*/
char tmp1[100],tmp2[100],tmp3[100];
sscanf("ABC_DEF_123","%99[^_]_%99[^_]_%99[^_]",tmp1,tmp2,tmp3);
printf("tmp1=%s, tmp2=%s, tmp3=%s;\n",tmp1,tmp2,tmp3);

Any ideas ???

Okay I am sorry!!!

Its working. It was my error internally.
Now How do I grade you ? Because Now I don't have any options
of giving you the grade ?

By the way ozo, is it possible to scan the last item "123"
to be an integer ?

That is instead of char tmp3[100] being "123"
i want int tmp3=123 ?

Is this possible using sscanf ?
