If you put this out c++ shell you will be able to see the problems. Here is the link http://cpp.sh/ Can anyone help? #include <iostream> #include <fstream> #include <string> #include <iomanip> // Function prototypes void PrintFileContents(std::ifstream& ifile); void ProcessAccounts(std::ifstream& ifile, std::ofstream& ofile, double); void SetInputStreamPos(std::ifstream &str, int pos); void SetOutputStreamPos(std::ofstream &str, int pos); std::ifstream GetInputFile(std::string filename); //std::ofstream GetOutputFile(std::string filename); //[BEGIN MAIN] int main() { std::string inputFileName; std::string outputFileName; double interestRate; std::cout << "Enter an input filename: "; std::cin >> inputFileName; std::cout << "Enter an output filename: "; std::cin >> outputFileName; std::cout << "Enter an interest rate (%): "; std::cin >> interestRate; std::cout << std::endl; std::ifstream ifile = GetInputFile(inputFileName); std::ofstream ofile = GetOutputFile(outputFileName); std::cout << "Current account status:" << std::endl; PrintFileContents(ifile); ProcessAccounts(ifile, ofile, interestRate); ifile.close(); ofile.close(); std::cout << std::endl; std::cout << "New account status:" << std::endl; ifile = GetInputFile(outputFileName); PrintFileContents(ifile); ifile.close(); std::cout << "Press ENTER"; std::cin.ignore(); std::cin.get(); return 0; } //[END MAIN] void ProcessAccounts(std::ifstream &ifile, std::ofstream &ofile, double rate) { // Everyday the bank checks the status of the accounts and processes them // If the customer has: // 1) a positive savings balance, pay them interest // 2) a negative savings balance, transfer it to credit (credit is positive) // 3) a credit balance, charge them interest // Note: Unlike normal banks, the interest rate for savings and credit is the same // Read the info from the input file // Put the new info into the output file // The format for the input file and output file should be // [NAME] [SAVINGS BALANCE] [CREDIT BALANCE] // There is a single space between each value and a newline at the end // Put your code here std::string name; double sav_balance; double credit_balance; ifile >> name >> sav_balance >> credit_balance; while(!ifile.eof()) { //std::cout << name << " " << sav_balance << " " << credit_balance << std::endl; double sav_final=0; double credit_final=0; if(sav_balance > 0) // 1) a positive savings balance, pay them interest sav_final = sav_balance + sav_balance*rate; else if(sav_balance < 0) // 2) a negative savings balance, transfer it to credit (credit is positive) credit_final = credit_balance - sav_balance; if(credit_balance > 0) // 3) a credit balance, charge them interest credit_final = credit_final + credit_balance*rate; ofile << name << " " << sav_final << " " << credit_final << std::endl; //std::cout << name << " " << sav_final << " " << credit_final << std::endl; ifile >> name >> sav_balance >> credit_balance; } } void PrintFileContents(std::ifstream &str) { // Print the contents of the file // First, print the file headers // Then, print each line. // Make sure the text is properly formatted // Remember the functions available in iomanip? // EXAMPLE: // Name Savings Credit // Bob $23.56 $0.00 // Joe $43.52 $0.00 // Sally -$1.58 $0.00 // Put your code here std::string name; double sav_balance; double credit_balance; std::cout <<"Name Savings Credit" << std::endl; str >> name >> sav_balance >> credit_balance; while(!str.eof()) { std::cout << std::setprecision(2) << std::fixed << name << " $" << sav_balance <<" $"<< credit_balance << std::endl; str >> name >> sav_balance >> credit_balance; } } std::ifstream GetInputFile(std::string filename) { // Open the file named filename // Make sure it exists // Return it as an input file stream // Put your code here std::ifstream ifile; ifile.open(filename); if(!ifile.is_open()) { ifile.close(); } else; { std::cout <<"unable to open file so Exiting .." << std::endl; } return ifile; } std::ofstream GetOutputFile(std::string filename) { // Open the file named filename // Make sure it exists // Return it as an output file stream // Put your code here std::ofstream ofile; ofile.open(filename); if(!ofile.is_open()) { ofile.close(); } else { std::cout <<"unable to open file so Exiting .." << std::endl; } return ofile; } void SetInputStreamPos(std::ifstream &str, int pos) { // Set the 'g'et cursor to the desired byte in the stream // Use the beginning of the file as the reference point // Put your code here str.clear(); str.seekg(pos, std::ios::beg); } void SetOutputStreamPos(std::ofstream &str, int pos) { // Set the 'p'ut cursor to the desired byte in the stream // Use the beginning of the file as the reference point // Put your code here str.clear(); str.seekp(pos, std::ios::beg); }
