Project Solution

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:




1. Course Code (like HUM001)

2. Course Name (like Technical Writing)

3. Exam Date (like 28/4/2016)

4. Exam Location (like HallA)




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:




1. Student ID (like 12001)

2. Student Name(like Ahmed Hassan)

3. 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.













Operations




When the program start, the user enters one CoursesExams Line and one Students Line in the defined above format then followed by one or more operations from the below table (each operation in a line). The program ends when it reads Quit operation.

two consecutive exams he/she attend (not including the exam days) in case of first exam the StudyDays should

be 7.

This command should print

the StudyDays of a student

before certain CourseCode.

CourseCode
This command should print every student ID in a course followed by the StudyDays of that student for the given coursecode.
List_StudyDays_ForEveryCourse

This command should print every Course Code attended by the given student followed by the StudyDays of that course for the given student.
List_Minimum_Student_StudyDays

StudentID
This command should print the minimum StudyDays of all courses of the given student.
List_Minimum_Course_StudyDays

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:




1­ User can input up to 100 courses and up to 100 students.

2­ Each student can attend up to 10 courses.

3­ Graphics library and Time class can not be used in that project.

4­ All your code should be in one file.

5­ Do not prompt user to enter anything , just read the input directly and print the output of operations directly.

6­ At any operation if the output is empty the operation should print

“none”

7­ Output should not include any extra white spaces or any extra texts more than the results.

Hints:




1. You should write int main() and you should not write void main()

2. Never use system("pause");

3. 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;

}
