Project

Due Date for Project Submission:
Level1: Tuesday May 10th, 2016 (till 11:59PM).
Level2 and 3 and Extra: Monday June 27th, 2016 (till 11:59PM).

Teams: No Groups, Work is individual based (Each Student submit a project).

Automatic Grading will be applied over an online system.
Use the Submission Manual that explains how to register on the online system and submit, test/evaluate your code.
The online system can automatically detect copied submissions with intelligent comparison (plagiarism detection). All detected copies of students submissions will take zero grade.

Project Description

It is required to develop a program to do operations on courses, exams and students data. The program use a defined string format to represent courses exams and students. All courses exams will be in one line input, and all students will be in one line input. For example:

CoursesExams=[HUM001,Technical Writing, 28/4/2016, HallA;CSE121,Computer Programming,3/5/2016, HallB]
Students=[12001,Ahmed Hassan, (CSE121,HUM001);12002,Aly Hamed,(CSE121)]

Courses Exams Data

The CoursesExams line contains a list of courses exams data separated by ‘;’. Fields of a course exam are:

Course Code (like HUM001)
Course Name (like Technical Writing)
Exam Date (like 28/4/2016)
Exam Location (like HallA or like 244 or like CSELab)

Data of the same course exam are separated by comma as shown in the above example. User can enter data for up to 100 courses exams in one line separated by ; as shown in the above example.

Students Data

The Students line contains a list of students data separated by ‘;’. Fields of a students are:

Student ID (like 12001)
Student Name(like Ahmed Hassan)
Course codes of student attended courses (like (CSE121,HUM001)). One student can attend up to 10 courses.

Students data of the same student are separated by comma as shown in the above example. User can enter data for up to 100 students in one line separated by ; as shown in the above example.

And such that the StudyDays of all students of that course should be at least (MinDays). The chosen date should be in the given date range.

Project Marks Distribution:

40% to support operations in Level 1

30% to support operations in Level 2

30% to support operations in Level 3

20% for Extra Marks Part

General Constraints:

User can input up to 100 courses and up to 100 students.
Each student can attend up to 10 courses.
Graphics library and Time class can not be used in that project.
All your code should be in one file.
Do not prompt user to enter anything , just read the input directly and print the output of operations directly.
At any operation if the output is empty the operation should print “none”
Output should not include any extra white spaces or any extra texts more than the results.

Hints:

You should write int main() and you should not write void main()
Never use system("pause");
While parsing data, you will need to convert from string to a number.
Use atof() function defined in <cstdlib>.
The conversion code is f=atof(s.c_str());
Use the following example as a guide:

#include<iostream>
#include<string>
#include<cstdlib>

using namespace std;

int main() {
// To convert from string to float use atof function
// atof needs #include<cstdlib>

string s = "1.5";
float f;
f = atof(s.c_str());

return 0;
}
