i have this so far and not sure if im going in the right direction

#include <iostream>
#include <iomanip>

using namespace std;

const double ESN = 90.00;
const double RRC = 200.00;
const double ACR = 250.00;
const double FC = 400.00;
const double M = 30.00;
const double D = 35.00;

int main()
{

	int sid, uni, rc;
	char r_type, grad;
	double cfu, total;

	cout << "Student ID number: ";
	cin >> sid;
	cout << endl;

	cout << "Type of room(R/A): ";
	cin >> r_type;
	cout << endl;

	cout << "# of units: ";
	cin >> uni;
	cout << endl;

	cout << "Are you graduating?(Y/N): ";
	cin >> grad;
	cout << endl;

	cfu = uni * ESN;


	switch (r_type)
	{
	case 'r':
	case 'R':
		r_type = RRC;
		break;
	case 'a':
	case 'A':
		r_type = ACR;
		break;
	default:
		cout << "Incorrect room type. Room charge not calculated." << endl;
	}
	switch (grad)
	{
	case 'y':
	case 'Y':
		total = r_type + cfu + M + D;
		break;
	case 'n':
	case 'N':
		total = r_type + cfu + M;
		break;
	}

	if (uni > 21)
	{
		cout << "this is not allowed." << endl;
		system("pause");
		
	}
	if (uni < 12)

		cout << "not full time student" << endl;

	
	cout << "Student ID" << setw(10) << sid << endl;
	cout << "Units" << setw(10) << uni << endl;
	cout << "Charge for units" << setw(10) << cfu << endl;
	cout << "Room charge" << setw(10) << rc << endl;
	cout << "Food charge" << setw(10) << FC << endl;
	cout << "Matriculation Fee" << setw(10) << M << endl;
	cout << "Total semester charges" << setw(10) << total << endl;




	return 0;
