apecifying fielf size with width() in C++.

 



#include <iostream>
using namespace std;
int main()
{
    int item[4] = {10, 5, 8, 34};
    int cost[4] = {20, 34, 23, 4};

    cout.width(5);
    cout << "ITEMS";
    cout.width(8);
    cout << "COST";
    cout.width(15);
    cout << "TOTAL PRICE\n";
    int sum = 0;
    for (int i = 0; i < 4; i++)
    {
        cout.width(5);
        cout << item[i];
        cout.width(8);
        cout << cost[i];
        int value = item[i] * cost[i];
        cout.width(14);
        cout << value << endl;

        sum = sum + value;
    }
    cout << "GRAND TOTAL = " << sum;
}

output:
ITEMS COST TOTAL PRICE 10 20 200 5 34 170 8 23 184 34 4 136 GRAND TOTAL = 690

Assume that a bank maintains two kinds of accounts, are called as saving account and current account. The saving account provides compound interest and withdrawal facilities but no cheque book facility. The current account provides cheque book facility but no interest. Current account holders should also maintain a minimum balance and if the balance falls below the level, a service charge is imposed. Create a class account that stores customer name, account number and type of account. From this derive the classes cur_acct and sav_acct to make them more specific to their requirements. Include necessary member functions in order to achieve the following tasks: a.Include constructor for all the three classes. b.Accept deposit amount from the customer and update the balance. c.Display the balance. d.Compute and deposit interest. e.Permit withdrawal and update the balance. f. Check for minimum balance, impose penalty, necessary and update the balance.
