An Example of a Low Level Abstraction, Sorting Employee Records

class Employee {
public:
	string name;
	int salary;
	int startingYear;	
}

void sort (Employee * data[ ], int n) {
	for (int i = 1; i < n; i++) {
		int j = i-1;
		while (j >= 0 && 
		   v[j+1]->startingYear < v[j]->startingYear) {
			// swap elements
			Employee * temp = v[j];
			v[j] = v[j+1];
			v[j+1] = temp;
			j = j - 1;
		}
	}
}
