array sorting in randomly - c

Question

i have below code, that i expect should read text from file, store words in array and then print it out in random order. Final array is int, but should be char and it does not give me proper answer.
#include<stdio.h>
#include<string.h>
#include <stdlib.h>
#include <time.h>
int main()
{
char message[10][150], buffer[150];
int i = 0;
int cntr = 9;
char freeArray[9];
srand(time(NULL));
freeArray[i] = rand() % cntr;
FILE *file_in;
file_in = fopen("test.txt", "r");
while (fgets(buffer, 150, file_in))
{
i = rand() % cntr;
strcpy(message[freeArray[i]], buffer);
}
while (cntr >= 0)
{
i = rand() % cntr;
strcpy(message[freeArray[i]], buffer);
freeArray[i] = freeArray[cntr--];
printf("%s", freeArray[i]);
}
return 0;
}
I have alternative code, but this one gives me text without shuffle.
#include<stdio.h>
#include<string.h>
#include <stdlib.h>
#include <time.h>
int main()
{
/*declare and initialise variable*/
char message[10][150],buffer[150];
int i=0;
int j;
srand(time(NULL));
FILE *file_in;
file_in=fopen("test.txt", "r");
/*stores and prints the data from the string*/
while(fgets(buffer,150,file_in)){
strcpy(message[i],buffer);
}
while(i < 10)
{
j = rand() % 10;
printf("%s\n",message[j]);
i++;
}
return 0;

Answer 1

The following code:
-- compiles cleanly
-- contains all the changes needed to the OPs posted code
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#define MAX_MESSAGES (10)
#define MAX_MESSAGE_LEN (150)
static char message[MAX_MESSAGES][MAX_MESSAGE_LEN] = {{'\0'}};
static char buffer[MAX_MESSAGE_LEN] = {'\0'};
int main()
{
/*declare and initialise variable*/
int i=0;
int j;
FILE *file_in;
if( NULL == (file_in=fopen("test.txt", "r") ) )
{ // then, fopen failed
perror( "fopen failed for test.txt" );
exit( EXIT_FAILURE );
}
// implied else, fopen successful
srand(time(NULL));
/*stores and prints the data from the string*/
while( (i<MAX_MESSAGES) && fgets(buffer,150,file_in) )
{
strcpy(message[i],buffer);
i++;
} // end while
printf("\ndisplay %d messages in random order\n", MAX_MESSAGES);
printf("with possible repeated messages and skipped messages\n");
for( i=0; i < MAX_MESSAGES; i++)
{
j = rand() % MAX_MESSAGES;
printf("message: %d: %s\n",j, message[j]);
} // end for
return 0;
} // end function: main

The following is to answer the question given in an answer block
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
//#include <time.h>
#define MAX_MESSAGES (10)
#define MAX_MESSAGE_LEN (150)
static char message[MAX_MESSAGES][MAX_MESSAGE_LEN] = {{'\0'}};
static char buffer[MAX_MESSAGE_LEN] = {'\0'};
static char t[MAX_MESSAGE_LEN] = {'\0'};
int main()
{
/*declare and initialise variable*/
int i=0;
int j = 0;
FILE *file_in = NULL;
if( NULL == (file_in=fopen("test.txt", "r") ) )
{ // then, fopen failed
perror("fopen for test.txt failed");
exit( EXIT_FAILURE );
}
// implied else, fopen successful
/*stores, sorts and prints the data from the string*/
i = 0;
while( (i<10) && (fgets(buffer,150,file_in)) )
{
strcpy(message[i],buffer);
i++;
} // end while
for (i = 1; i < 3; i++)
{
for (j = 1; j < 3; j++)
{
if (strcmp(message[j - 1], message[j]) > 0)
{
strcpy(t, message[j - 1]);
strcpy(message[j - 1], message[j]);
strcpy(message[j], t);
} // end if
} // end for
} // end for
printf("\nStrings in order are : ");
for (i = 0; i < 3; i++)
{
printf("message: %d: %s\n", i+1, message[j]);
} // end for
getchar();
return 0;
} // end function: main
