for loop to read details for employees

Question

Should company name be XYZ & in the for loop body i want to enter staffNo/DeptID/AnnualSalary.

What does this code mean:
cin >> XYZ[i].staffNo;

Answer 1

Without the entire code, it lacks context for telling what the snippet signifies. However,

XYZ is supposed to be an array of class or struct objects (supposingly class/struct staff) which at least has the structure of:

struct staff
{
int staffNo;
};

The original declaration of the array of class/struct object would be:

staff* XYZ = new staff[n];

where n is the number of staff objects. The member of each object can then be initialized with user input via the statement

cin >> XYZ[i].staffNo;

inside a for loop.

Answer 2

For(int i=0; i < 5;i++)
{
cout << “Enter staff no of the employee “<< endl;
cin >> XYZ[i].staffNo;
}
I need to understand what this line means in context or any link that may refer me to more practice in this.

cin >> XYZ[i].staffNo
