Answer
Hai Dear Bita !

 Your code having simple issue , ie you failed to terminate the string using the null character that's why your program displaying some garbage value !!

#include<stdio.h>

void main()
{
  int i = 0;

  char ch , word[80];
  while( (ch = getchar()) != '\n')
     word[i++] = ch;
  word[i] = '\0'; /* Terminating the string using null value */
  printf(" The string is :");
  puts(word);
}


Thanks and Regards !
