- It's important to distinguish between a data member and a local variable.The similarities between a pointer and a reference.Question IV: ER Modeling A social recreation club has a system to keep track of club members, committees and activities. Each club has a registration number and a title. Several members form committee. Members are male and females. Each committee has a name, a unique number and a date, which the committee has formed. The system stores the members’ unique identification number, name, address, gender, birth date and club joining date. The club forms committees for different activities. A committee controls and organizes a number of activities, each of which has a unique name, a unique number and description of the event. An event has event ID and description of the event. An activity may consist of several events. Committee publishes many online advertisements about the activities. Advertisement details are ID and a title. Draw the ER diagram to represent the above scenario
