While loop stuck after processing last line of array in C

Hi all below is my code which gets stuck at "if((p_note_for_sm[msg_line_no]) != NULL)" in function "int Ms_SEnd(char **p_note_for_sm)" , After debugging the if condition i found that the value of p_note_for_sm[msg_line_no] is not getting printed after processing upto last character of array and program unable to break from while loop and program gets stuck . (i expect the value NULL in (p_note_for_sm[msg_line_no]) to break this loop ) , Kindly help me to find out the solution.

    #include <stdio.h>
    #include <string.h>
    #include <strings.h>
    #include <stdlib.h>
    #include <math.h>
    #define SMAXLINE              200

    int Ms_SEnd(char **p_note_for_sm)
    {
        int msg_line_no=0;

            while(msg_line_no <= 200)
       {
        if((p_note_for_sm[msg_line_no]) != NULL)
            {
              if(strcmp(p_note_for_sm[msg_line_no],"\0") != 0)
              {
                  printf("\nMsg In SM loop inside [%s]",p_note_for_sm[msg_line_no]);    
              }
