C language: How to get the remaining string after using strtok() once

Question

My string is \"A,B,C,D,E\"
And the separator is \",\"
How can I get the remaining string after doing strtok() once, that is \"B,C,D,E\"

char a[] = \"A,B,         


        

Answer 1

Don't use strtok() for this, since that's not what it's for.

Use strchr() to find the first separator, and go from there:

char a[] = "A,B,C,D,E";
const char separator = ',';
char * const sep_at = strchr(a, separator);
if(sep_at != NULL)
{
  *sep_at = '\0'; /* overwrite first separator, creating two strings. */
  printf("first part: '%s'\nsecond part: '%s'\n", a, sep_at + 1);
}
