Assignment No.  2

Semester: Spring 2020
CS201 – Introduction to Programming Total Marks: 20

Due Date:
16-6-2020

Instructions
Please read the following instructions carefully before submitting assignment:
It should be clear that your assignment will not get any credit if:

o Assignment is submitted after due date.
o Submitted assignment does not open or file is corrupt.
o Assignment is copied (From internet/students).

Software allowed to develop Assignment

  • Dev C++

Objectives:
In this assignment, the students will learn:
• How to fill / populate a two-dimensional array using given source data.
• How to write user defined functions and pass an array to them as parameter.
• How to use if statement and do while loop.
• How to calculate the percentage in elements of array.
• How to display array elements.

Assignment Submission Instructions
You are required to submit only .cpp file on the assignments interface of CS201 at VU-LMS. Assignment submitted in any other format will not be accepted and will be graded zero marks.

Problem Statement
Write a menu in C++ which should show the country code and name at the start of application:

  1. Press 0 for Pakistan.
  2. Press 1 for China.
  3. Press 2 for Italy.
  4. Press 3 for UK.
  5. Press 4 for Iran.
  6. Press 5 for France.
  7. Press 6 for Turkey.
  8. Press 7 to exit.
    Instructions to write C++ program:

 Write functions to calculate % of recovered patients, % of deaths in specific country . Following function names should be used for consistency.

To display all elements in matrix form showElements( );
Percentage of death PercentageDeath ( ):
Percentage of recovered PercentageRecovered();

Source data:

Country Code Total Cases Total Deaths Total Recovered
0 560,433 22,115 32,634
1 156,363 19,899 34,211
2 84,279 10,612 0
3 82,160 3,341 77,663
4 71,686 4,474 43,894
5 56,956 1,198 3,446
6 5,374 93 1095

Sample Output:
First, user will call the showElements() method to display all the data in matrix form:
Then, it will display a menu to calculate the percentage of dead and recovered persons for specific country:

If user presses 0 then it will show the percentage of dead and recovered persons for Pakistan:

If user presses 1 then it will show the percentage of dead and recovered persons for China:

If the user enters option other then 0 to 7. Following messages display:
Choice should be between 0 and 7
Invalid choice, please select again:
