Assalamualaikum..

First of all,we would like to express our appreciation for the

loving support we have received from our lectures,who have

helped us in our quest to complete this project, Dr Junita

Mohamad.Now,we realize how powerful c++ program can be as asoftware.It would be a hard and difficult task to complete this such

of project,but with the c++ software and guidance from our

lectures,this project has made a lot easier for us.

Also,we would like to take this opportunity to thank those who

have made this project a success especially to our lecturers,

collegues, friends and seniors at Universiti Sains

Malaysia,especially those from the school of Electrical andElectronic Engineering.

.

Thanks to all.

This project is our first mini project in c++computer programming.After we have discussedabout what we want to do in this project,finally wehave decided to quadratic equation in our

programming.In this project,our objectives is we try to solve

the equation by using [b-(b-4ac)]/2a formula.Its means,when the user input the number for a,band c in the equation,program will run to display theroot according [b-(b-4ac)]/2a formula.If b-4ac=0, then the root is real root.Meanwhile if b-

4ac>0,the equation has real and distict root.For thecomplex root ,must cater b-4ac

WEEK DIVISION OF WORK

WEEK 8 Every person in our groupmust find as many information

as possible.WEEK 9 Combine all the informationtogether and choose the bestinformation to be used inprogramming

WEEK 10 Study how to do programming

correctly and excellently fromthe seniors or person whoexcel in C++ programming

WEEK 11 Start to do programmingWEEK 12 Continue to do programming

and check any error that has

been doneWEEK 13 Do double checking for errorand try to debug

WEEK 14 Presentation starts

PSEUDOCODE1.Start the program2.Declare the function prototype

3.Ask user to enter value for a,b and cthat contain in the quadratic equation.4.The program will detect the rooteither it is real root or complex root5.The program will call the function and

display the root by using given formula.6.End of the program.

After compiling our programs,we have

tried key in a number in the equation and

the program display the correct answer.We

have also tried our program with various

equation and the roots obtain accurately.This

survey also proved that our program is

correct.

Our project was a success though we have met

many unexpected roadblocks along the way. We

have checked our program multiple times and

tested its effectiveness with users around the

campus as well as other programmers. Throughthis survey, we have realized that our program is

user friendly and easy to understand. Our

program is also unique and effective due to

some tough equation that we have chosen to test

the accuracy of our program.
