## Instructions

It should be clear that your assignment will not get any credit if:

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

### Recommended tool to develop Assignment

• Dev C++

Objectives:

To enable students to understand and practice the concepts of:

• Data Types and Variables
• Arithmetic and Logical Operators
• Expression solving
• If-else statements
• repetition structure

### Assignment Submission Instructions

You have to submit only.cpp file on the assignments interface of CS201 from your LMS account. Assignment submitted in any other format will be scaled with zero mark. So, check your solution file format before submission.

Lectures: 1 to 6

### Assignment Question

An expression is given here. You are required to write a C++ program that solves the given mathematical expression.

Z = x2 + 2xy – x/y

set the values of x = 2 and y = 1

Three main tasks are to be done by each student:-

1. Expression solving
2. Decisions making (if-else structure)
3. Repetition structure (while loop).

After evaluation of above expression, you should add the value of z to last digit of your vu id. As a result,

1. If you get an odd number, then you should print your VU id using while loop. This while loop should run as many times as odd number you got from (z+ last digit of your vu id).

For example, suppose the value of z is 2 and the student’s id is BC123456781. Then by  adding last digit of vu id 1 to value of z, result will be 3 which is an odd number. In this case, program should print your VU ID for 3 times using while loop.

Sample screen shot::

1. If you get an even number, then you should print your Name using while loop. This while loop should run as many times as even number you got from (z+ last digit of your vu id).

For example, suppose the value of z is 2 and the student’s id is BC123456782. Then by  adding last digit of vu id 2 to the value of z, result will be 4 which is an even number. In this case, program should print your Name for 4 times using while loop.

``````#include <iostream>
using namespace std;
main()
{
int x,y,z, vid=6,i=1;
x=2; y=1;
z= x*X + 2*x*y-x/y;
cout<<"After evalution of expression z values is :" << z<<end1;
cout<<"Last digit of my vu id is :" <<vid<<end1;
vid= vid +z;
if(vid%2==1)
{
cout<< "i got an odd number "<<vid<<end1;
while(i<=vid)
{
cout<< "iteration :"<<i<<end1;
cout<<"my vu is id BC200202206"<<end1;
i++;
}
}
else
{
cout<< "i got an even number "<<vid<<end1;
while(i<=vid)
{
cout<<" iteration :"<<i<<end1;
cout<<"my name is Fatima "<<end1;
i++;
}
}
