Need help with vectors and arrays

[bigyankeefan]

I am in need of assistance with a homework assignment where I have to write a program that prints out a bank statement .The program input is a sequence of transactions with each transaction having the following: day, amount, description. The program should read in the descriptions and then print out a statement listing all deposits, withdrawals and the daily balance for each day. Then compute the interest earned by the account. The minimum and average daily balances methods should be used for computing interest and print out both values. An interest rate of .5% per month with the assumption that each month has 30 days with the data sorted by date. The first entry is the form of: 1 1143.24 initial balance.

This what I have thus far:

header

# include<iostream.h>
# include<conio.h>
# include<iomanip.h>

class bank

{

char name[20];

int acno;

char actype[4];

float balance;

public:

void init();

void deposit();

void withdraw();

void disp_det();

};

void bank :: init()

{

cout<<"New Account";
cout<<"Enter the Name of the depositor : ";
cin.get(name,19,'');

cout<<"Enter the Account Number : ";

cin>>acno;

cout<<"Enter the Account Type : (CURR/SAVG/FD/RD/DMAT) ";

cin>>actype;

cout<<"Enter the Amount to Deposit : ";

cin >> balance;

}

void bank::deposit()

{
float more;
cout <<"Depositing";

cout<<"Enter the amount to deposit : ";

cin >> more;

balance+=more;

}

void bank::withdraw()

{

float amt;

cout<<"Withdrwal";

cout<<"Enter the amount to withdraw : ";

cin >> amt;

balance -=amt;

}

void bank::disp_det()

{

cout<<"Account Details";

cout<<"Name of the depositor : "<< name << endl;

cout<<"Account Number : "<< acno << endl;

cout<<"Account Type : "<< actype << endl;

cout<<"Balance : $"<< balance << endl;

}

void main(void)

{

clrscr();

bank obj;

int choice =1;

while (choice != 0 )

{

cout<<"Enter 0 to exit

1. Initialize a new acc.
2. Deposit

3.Withdraw

4.See A/c Status";

cin>>choice;
switch(choice)

{

case 0 :obj.disp_det();

cout<<"EXITING PROGRAM.";

break;

case 1 : obj.init();

break;

case 2: obj.deposit();

break;

case 3 : obj.withdraw();

break;

case 4: obj.disp_det();

break;

default: cout<<"Illegal Option"<<endl;

}

}

getch();

}

You didn't explain what your problem is. Not too many people are going to read through 400 lines of poorly formatted code.

To have a better chance of getting help, state exactly what is wrong with your code and try to isolate it to a few lines or concepts.
