First of all, thanks for the idea! I have a serious problem. This is the code I've written:

Code:

int i, row;
void *index;
char *row_n, *result, word[15], keystrokes[20][81];

printf("Word to find: ");
fgets(word, sizeof(word), stdin);

     for (i=0;i<20;i++)    /* 20 lines */
     {
         row_n=keystrokes[i];
         if ((result=strstr(keystrokes[i],word))!=NULL)     /* keystrokes[i]=&keystrokes[i][0] */
         {    
             index=result-row_n;
             row=i;
             gotoxy(index,row);
         }
         else
        {
             printf("There's No Such Word");
        }
     }

My program crashes when I run this code. Is the code properly written? How can I find the index of that pointer in the array and what about the gotoxy(col,row) function?
