    trying to use strtok

    i am a beginner in C programming, and i appreciate any help with strtok. what i wanna do is for the program to scan the data, and whenever it encounters the alphabet "l", the section before the alphabet "l" would be copied to a string array. for instance,
    Code:
    #include <stdio.h>
    #include <string.h>
    main ()
    {
     char *b;
      int i,;
      char s[100];
      char data[100];
    
      strcopy(data,"asdldsaldsal");
    
      for(i=0;i<=2;i++)
        {
          b = strtok (data,'l');
          s[i]=b;
     
      if (s[i]==NULL)
        break;
        }  
     printf("s[1]=",s[1]);
    
      return 0;
    }
    why doesnt it run? thank you for your attention...

    sincerely

    Look up the function usage for strtok. The first call passes a pointer, but subsequent calls require the passing of NULL.

    There is also no function strcopy, you were looking for strcpy.

    I'd suggest starting with simpler programs before diving into arrays and pointers.

    It's not the simplest of questions though, I find using strtok() a bit annoying somtimes.
