Question

Required to develop a complete C Program (runs in Dev-C++ software) that helps to manage the records of projects in an Engineering Students Design Project competition organized by a university. The actual number of projects are unknown, but it is limited to a maximum number of 100.

Each project record contains information like Project ID, Project Title, Name of Team Members and Scores of evaluation. These project records are stored in a text file, sorted by the project id. A sample text file is given as follows,

101; Intelligent vacuum cleaner; Andrew, Bryan and Cecilia; 16;24;20;22; 102; Smart home system; Danesh and Elaine; 18;20;16;21; 104; Rubik's cube solver; Fatimah and Ganesh; 16;22;18;20;

The criteria of the project evaluation are

(a) Originality and innovativeness: 20%
(b) Scientific approach and technical design: 30%
(c) Result and project outcome: 25%
(d) Presentation and demonstration: 25%

The top three highest scores will be awarded. In addition, a Best Engineering Design award will be selected based on criteria (b).
The software reads projects’ details from file, and it should be a menu driven system having the following minimum options:

1. Add a New Project record (must keep the list ofProject Records sorted by the Project ID), and update the data file,
2. Print the summary of Project Details, i.e., Project ID, Title, Members’ Nameand Total Score, ranking from highest to lowest total score of evaluation,
3. Print the details of the winner Projects, i.e., Project ID, Title and Members’ Name,
4. Accept query of Project ID, andPrint the Score of evaluation by criteria.

Answer 1

// Though I have checked and compiled the program, if you found any mistake or something that I might have interpreted wrong, please comment on it.
// I will correct that as soon as possible. :)

//I am assuming the project ID is always a three digit number.
//if at any point in the code you see fscanf(fptr, "%c", &c);
// it is only because in the input there was an extra character that we dont need
