- Case study: You are required to develop an application to keep track of meeting minutes. Every time a formal meeting takes place, corresponding meeting minutes should be generated. Each meeting has a list of participants, which the system receives from the caller of the meeting. The caller also assigns the role of meeting secretary to one of the participants. The contents of the minutes are usually text, however, images and audio clips can also be attached to the minutes. The number of attachments is not limited. For each meeting, minutes can only be created by the assigned meeting secretary (for that meeting), who is also responsible for uploading the attachments. Minutes can be created incrementally. Once the secretary is satisfied with his/her draft, the minutes can be broadcast to the participants, who can then make comments on the minutes. Participants can make comments on the minutes as a whole. These are global comments. They can also select particular sections of the minutes…Student – with no parameters, initialize all the data members to 0 or null.
