Write a class with name String. Assume, only stdio.h library is included and it is not possible to include any other library. In private section of class there will be a character array (lets say s) and also it is possible to locate functions to this section that you want to use but not asked. In public section there will be five functions,

(i) set function will take a character array as parameter and assign it to s

(ii) print function will just print s on screen

(iii) count function will find and return number of consonants in s (vowels: i,o,u,e,a).

(iv) show function will take an integer as parameter and print a portion of s after that count number of characters which is taken as parameter.

(v) postfix -- operator will delete the last character of s.
