A shopping mall announces a special discount on all its products as a festival offer only to those who satisfy any one of the following conditions.
- If he/she is an employee of the mall and has a service of more than 10 years.
OR - A regular customer of the mall whose age is less than 65 years and should not be an employee of the mall.
OR - If he/she is a senior citizen but not a regular customer of the mall.
The inputs are:
| INPUTS | |
| E | Employee of the mall |
| R | Regular customer of the mall |
| S | Service of the employee is more than 10 years |
| C | Senior citizen of 65 years or above |
(In all the above cases, 1 indicates yes and 0 indicates no.)
Output: X - Denotes eligible for discount [1 indicates YES and 0 indicates NO in all cases]
Draw the truth table for the inputs and outputs given above and write the SOP expression for X ( E, R, S, C ).

Design a class Check which checks whether a word is a palindrome or not.
(Palindrome words are those which spell the same from either ends).
Example: MADAM, LEVEL etc.
The details of the members of the class are given below:
| Class name | Check |
| Data members/instance variables: | |
| wrd | stores a word |
| len | to store the length of the word |
| Methods/Member functions: | |
| Check( ) | default constructor |
| void acceptword( ) | to accept the word |
| boolean palindrome( ) | checks and returns ‘true’ if the word is a palindrome otherwise returns ‘false’ |
| void display( ) | displays the word along with an appropriate message |
Specify the class Check giving details of the constructor, void acceptword( ), boolean palindrome( ) and void display( ). Define the main( ) function to create an object and call the functions accordingly to enable the task.

Design a class Toggle which toggles a word by converting all upper case alphabets to lower case and vice versa.
Example: The word “mOTivATe” becomes “MotIVatE”
The details of the members of the class are given below:
| Class name | Toggle |
| Data members/instance variables: | |
| str | stores a word |
| newstr | stores the toggled word |
| len | to store the length of the word |
| Methods/Member functions: | |
| Toggle( ) | default constructor |
| void readword( ) | to accept the word |
| void toggle( ) | converts the upper case alphabets to lower case and all lower case alphabets to upper case and stores it in newstr |
| void display( ) | displays the original word along with the toggled word |
Specify the class Toggle giving details of the constructor, void readword( ), void toggle( ) and void display( ). Define the main( ) function to create an object and call the functions accordingly to enable the task.
