How to pass a array of strings to a function?

In the following program i just try to copy some string to the array and print it in another function.

I am getting segmentation fault .Could someone point out what i did wrong ? 

  #include <stdio.h>
  #include <string.h>
  #define MAX_STR_LEN 20

  void print_str(char str[][],int count);

  int main()
  {
      char str[2][MAX_STR_LEN];
      strncpy(str[0],"hello",MAX_STR_LEN);
      strncpy(str[1],"world",MAX_STR_LEN);
      print_str(str,2);
      return 0;
  }
  void print_str(char str[][],int count)
  {
      int i;
      for(i=0;i<count;i++)
      printf("%s\n",str[i]);
  }

Provide the second dimension length in a 2-D array in C always. First dimension length is optional if you are declaring a 2-D array.

We need to specify the column size mandatory when passing a 2D array as a parameter.

So, You should declare your function like this:

void print_str(char str[][MAX_STR_LEN],int count);

Use

void print_str(char str[][MAX_STR_LEN], int count);
