נושא: למה התוכנית לא רצה?!?

הנה בצורה יותר מובנת :


#include <stdio.h>
#include <stdlib.h> 
#include <string.h> 

char *sentence(char ** words){

    char *newstring, *save;
    int     length, lines;

    for(lines = length=0;  ; lines++){
        length = length + strlen(*(words + lines) ) + 1;
        if(*(*(words + lines) + strlen(*(words + lines)) - 1) == '.')
            break;
    }

    newstring = (char *)malloc(length * sizeof(char));
    newstring[0] = '\0';
    for( save = *(words) ; *(words) <= save + lines ; *(words) ++){
        strcat(newstring, *(words));
        if(*(words) < save + lines)
            strcat(newstring, " ");
        else
            newstring[length - 1] = '\0';
    }
    return  newstring;
}

   void maim()
   {
       char *words[]={{"a"},{"picture"},{"is"},{"worth"},{"a"},{"thousand"},{"words"}};
       char *word=sentence(words);
       puts(word);
     
   }

זו הגרסא הסופית

#include <stdio.h>
#include <stdlib.h> 
#include <string.h> 

char *sentence(char ** words){

    char *newstring, *save;
    int     length, lines;

    for(lines = length=0;  ; lines++){
        length = length + strlen(*(words + lines) ) + 1;
        if(*(*(words + lines) + strlen(*(words + lines)) - 1) == '.')
            break;
    }

    newstring = (char *)malloc(length * sizeof(char));
    newstring[0] = '\0';
    for( save = *(words) ; *(words) <= save + lines ; *(words) ++){
        strcat(newstring, *(words));
        if(*(words) < save + lines)
            strcat(newstring, " ");
        else
            newstring[length - 1] = '\0';
    }
    return  newstring;
}

   void maim()
   {
       char *words[]={{"a"},{"picture"},{"is"},{"worth"},{"a"},{"thousand"},{"words."}};
       char *word=sentence(words);
       puts(word);
     
   }
