Question-1

 

Suppose that you have a text file named contacts.txt listing name (maximum 15 characters), last name (maximum 15 characters) and birth date (in the format dd.mm,yyyy) of people. We do not know how many records are given in that text file but we know that there are at most 100 records in that file. A sample text file is provided below.

 

contacts.txt

LINDA WILLIAMS 02-04-1980

BARBARA BROWN 09-01-1995

ELIZABETH JONES 29-05-1960

JENNIFER MILLER 15-08- 1985

 

MARIA DAVIS 19-06-1999

 

 

 

Write a C program and:

 

  • Create a structure named date, to store day, month and year of the date.

 

  • Create another structure named contact to store each person’s name, lastname and birth date information.

 

  • Write a function named loadContact to read all records of the text file txt in an appropriate way.

 

  • Your main program should then list all contacts whose age is in between 18 and 25 in the format provided in sample run below.

 

Sample run for the given input file:

 

  1. JOHNSON, 18
  2. BROWN, 23
  3. DAVIS, 19

 

 

 

 

 

Question-2

 

Write a C program to implement an encryption algorithm described below. In this encryption technique, each letter of a given input word is replaced by a letter some fixed number of positions down the alphabet.

 

 

 

 

 

Your program will input a word and an integer value as input values. The integer value indicates the number of position each letter of the word has been moved down. You are given the following sample runs as examples.

 

Sample Run-1

 

Enter a word: computer

Enter a number: 4

 

Encrypted text: gsqtyxiv

 

 

 

Sample Run-2

 

Enter a word: ZOEY

 

Enter a number: 4

Encrypted text: DSIC

 

 

 

Sample Run-3

 

Enter a word: CScience

 

Enter a number: 5

Encrypted text: HXhnjshj

 

 

 

 

 

 

Hints:

 

You are given a sample C program which reads name and phone number from a file and prints in the console.
