Mr. Yuganda is an astrologer. To impress people, he asks people their
birth date & immediately tells them the day when they were born and number of
Sundays in that year. For e g, he asked me my birth date i.e., 23rd July 1989.
And he said me that it was Sunday, which was correct and number of Sundays
are 53. Your task is to write a program which will prove that it is simple work to
calculate day and number of days in that year when user enters any date. Your
program should ask for date, month, year separated by “/”. If it is VALID then it
should print the day.
e.g.
Input:
Enter the date : 23/07/1989
Output:
Entered date is 23rd April 1989
Leap year : NO
Day is Sunday
No. of days : 265
No. of Sundays : 53

Question 2 :
Write a program to print following pattern
11234
54322
33456
76544
55678
(Note there is no gap between two rows and numbers).
Question 3 :
I am always interested in interchanging the digits in the number. One day
I noticed that when I interchanged the position of the digits in the prime no., the
new number is also the prime number, but this is not possible for all prime
numbers. Then I came to the conclusion that some prime numbers are circularly
prime numbers.( A circular prime is a prime number that remains prime on any
cyclic rotation of its digits.)Find all such prime numbers up to the limit entered
and total count of the numbers.
Input
Enter the limit: 100
Output:
The numbers are: 2, 3, 5, 7, 13, 17, 37, 79
Total numbers are: 8

Question 4 :
Everyone is having interest in the rearrangement. Find all such
rearrangements possible with 0-9 digits without repetition of digits in the
number and count them. The number should CONTAIN distinct digits. The number
should not start from digit 0.
e.g.
Output
8547963120,1509784632.
Total numbers:

Question 5 :
Mr.Gaikwad always like to find the numbers which are Palindrome (A
palindrome is a word or sentence that reads the same forward as it does
backward e.g.121) in radix 10 (decimal numbers) and in given radix. Find all
such numbers and count them.Your program should take radix as input and
count all numbers upto 1000000.
Note : - Radix means base of that number.10-decimal,2-binary,8-octal,etc
Radix must be greater than 0 and less than 10.
e.g.
Input : -
Enter radix : - 2

Output : -
Decimal Radix -2
5 101
Total number : - ...
------------------------------------------------------------------------------------------------
Question 6 :
Write a program which prints the following pattern :
1 2 3 4 5 4 3 2 1
2 3 4 5 5 4 3 2
3 4 5 5 4 3
4 5 5 4
5 5
------------------------------------------------------------------------------------------------
Question 7:
File Handling is always very interesting part of C/C++ language. But the
information stored in the file might be understandable to other users, hence
some sort of cryptography is required. I think that reversing of the words in the
statement of the file is the better cryptography. Write a program to take input
file name which contain well indented matter, and your program should create
a new file which contains the line-wise reverse words but KEEPING the paragraph
same and display the contents of the new file.

e.g.
Suppose Code.txt contains the following data
C language was developed by Dennis Ritchie. It was developed in AT&T
Bell Labs.C language is the higher level language.
Input :-
Enter file name : Code.txt
Output : -
File name :-Crypt_code.txt
Contents: -
Ritchie Dennis by developed was language C. Labs Bell AT&T in
developed was It. Language level higher the is language C.
Questions 8.
I am a strong supporter of C language. I believe that any database can be
designed with using C-programming language. Support me by writing an
application that will perform following operations on the employee database
1.Insertion of record in the file
Note: - Employee database contains attributes Emp_no,
Name,Salary,Address,Pin_code,Phone_no.
2.Display the coloumn according to given ATTRIBUTE.
Code Frenzy Page 6 of 9
If you enter Name and Salary,then the output should be Name and
respective salary and it should be properly arranged in two columns. Your
program should take attributes as input from the user.
Sample Output:
Name Salary
Sunil Gaikwad 35000
Saurabh Atkari 30000
3. Sorting of the records According to the given attribute.
Your program should take input attribute from user and according that
attribute your program should sort the records in the file. Sorting must in
ascending order.
e.g.
Input : Name
Output :
Contents of the file
Name Salary
Saurabh Atkari 30000
Sunil Gaikwad 35000
Your whole program should go like this.
Code Frenzy Page 7 of 9
Menu
1. Insert a record in the file.
2. Display the records
3. Sort the records
4.Exit
Enter your choice :

Question 9:
Write a program which has a function which will execute before main()
and another function which will execute after main() function. And then prints
the following output , when in the respective blocks:
“Before main()”
“In main()”
“After main()”
