1) Modify program 1 to include a function getEndBalance that computes the ending balance of a savings account. The function takes three arguments that hold the starting balance, total deposits, total withdrawals and returns the ending balance. The ending balance is printed in main.

Below is program 1 with instructions which I already did. I computed the endbalance in the main but now you have to modify it to calculate the endbalance in the function.

Write a program that calculates the ending balance of several savings accounts. The program reads information about different customers accounts from an input file, accounts.txt. Each row in the file contains account information for one customer. This includes the account number, account type (premium, choice, or basic account), starting balance, total amount deposited, and total amount withdrawn.

Your program should:

• - open the file and check for successful open,

• - then calculate the ending balance for each customer account. The calculated data must

  be saved in an output file, accountsOut.txt, in a neat format as shown below. You may assume that the interest is 5% for premium accounts, 3% for choice accounts, and 1% for basic accounts.

  You MUST use a named constant for the interest rates. Since the results displayed are monetary values, your output must be displayed with two decimal places of precision. Be sure decimals line up when you output the final accounts information. And do not forget to close the files when done with them.

  Sample input file:

  234019 Premium 50100.44 25500.00 14792.91 234490 Choice 35000.52 14000.00 15780.88 347269 Premium 80400.00 28750.00 15598.70 239801 Basic 5504.29 1700.00 1600.76 487241 Basic 4023.00 1950.00 1500.00 982111 Choice 9245.00 12300.00 11768.98 

#include #include #include using namespace std;

//Constants const double Premium=0.05; const double Choice=0.03; const double Basic=0.01;

int main() { ifstream fin; ofstream fout; fin.open("accounts.txt");

if(!fin) { cout<<"Cannot open the input file"<

fout.open("accountsOut.txt");

}

int account; string type; double Startbalance; double deposit; double withdrawal; double endbalance;

fout<>account; fin>>type; fin>>Startbalance; fin>>deposit; fin>>withdrawal;

while(fin) { endbalance=Startbalance+deposit-withdrawal; if(type=="Premium") endbalance=endbalance+(endbalance*Premium); else if(type=="Choice") endbalance=endbalance+(endbalance*Choice); else endbalance=endbalance+(endbalance*Basic); fout<>account; fin>>type; fin>>Startbalance; fin>>deposit; fin>>withdrawal; } fin.close(); fout.close(); return 0;

}
