/*This program has an issue:

    *count is one more than the expected value
    *this may be because of fgets
Analysis os the issue:
    *The problem is found to be with fgets()
    *fgets only stops reading only after a \n is entered
    *So,\n is stored before '\0' which is an extra character which means count will be extra
  Solution:
    *Add -1 to the resultant and display it to the user
        --------------------OR--------------------
    *stop the loop of counting character when the character is \n (prefered)
