Answer 1

i use that function to split a string to string array

char  ** split(char *str, char *delimiter)
{
    char *temp=strtok(str,delimiter);
    char *arr[]={temp};
    int i=0;

    while(true)
    {
       elm=strtok (NULL, delimiter);

       if(!temp) break;

       arr[++i]=temp;
    }

    return arr;
}
