Dont forget to download the text file and copy it to the project file.

Someone came up with this solution(Not correct,but parts of them are reasonable):

Pls ONLY USE stdio,string,stdlib for this code!

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>
#include <ctype.h>

typedef int bool;

enum {
   false, true
};

//read fortune codes from file and store in the string 2D array
char *fortune_codes1[300];
char *fortune_codes2[300];

//count of number of codes
int size = 0;

void readFromText() {
   //count of number of codes
   int count = 0;
   char *line;
   size_t len = 0;
   //read the file: fortune_codes.txt
   FILE *fp;

The code itself doesn't work. Now I only want #include <stdio.h> #include <stdlib.h> #include <string.h>(three libraries) appear in the code. Pls modify the code or redo it(if you need to) to make sure it works and yield sample outputs. Pls run it before post the answer.
