After I press enter the code stops and lets me press enter forever; it won't terminate or proceed with the program. What do I do??? This is due in 1 hour help pls... T_T
Output:
Greetings!
Enter
number of banks would you like to analyze: 2
Please enter file name:
alpha_bank.txt
//Then after that it lets me press enter forever
and doesn't do anything
// also alpha_bank is a text file in the same folder
as this file
my code:
Code:#include <iostream>Code:#include <iomanip> #include <string> #include <fstream> #include <cmath> using namespace std; bool openAndVerify(ifstream &, string &); double averageCalc(ifstream &, string &); double stndrdDevCalc(ifstream &, string &, double); void print(double, double, string); string getBankName(ifstream &, string &); int main() { int counter, numDesired; double mean, stndrdDev; string bankName, fileName; ifstream inputFile; double min = 0; string betterBank; cout << "Greetings!\nEnter number of banks would you like to analyze: "; cin >> numDesired; counter = 0; while(counter < numDesired) { if(openAndVerify(inputFile,fileName) == false) { cout << "Error: bad file name. Program terminated!" << endl; return 0; } else { bankName = getBankName(inputFile, fileName); cout << bankName; mean = averageCalc(inputFile, fileName); stndrdDev = stndrdDevCalc(inputFile, fileName, mean); if (stndrdDev < min){ betterBank = bankName; } print(stndrdDev, mean, bankName); counter++; } } cout << betterBank << " is the preferred bank because it has the lowest standard deviation." << endl; return 0; } // PART A bool openAndVerify(ifstream &inputFile, string &fileName) { cout << "Please enter file name: "; cin >> fileName; inputFile.open(fileName.c_str()); if(inputFile.fail()) { inputFile.close(); return false; } else { inputFile.close(); return true; } } // PART B double averageCalc(ifstream &inputFile, string &fileName) { int numEntries = 0; double time, sum; sum = 0; inputFile.open(fileName.c_str()); inputFile.ignore(500, '\n'); //getline(inputFile, fileName) while(!inputFile.eof()) { inputFile >> time; sum += time; numEntries++; } inputFile.close(); return sum / numEntries; } // PART C double stndrdDevCalc(ifstream &inputFile, string &fileName, double mean) { int numEntries = 0; double time, stndrdDevCalcNumerator = 0; inputFile.open(fileName.c_str()); inputFile.ignore(500, '\n'); while(!inputFile.eof()) { inputFile >> time; stndrdDevCalcNumerator += pow((time - mean), 2); numEntries++; } inputFile.close(); return sqrt(stndrdDevCalcNumerator / (numEntries - 1)); } // Part D void print(double stndrdDev, double mean, string bankName) { cout << "===============================================" << endl; cout << "Bank Name: " << bankName << endl; cout << setprecision(1) << showpoint << fixed; cout << "Average wait time: " << mean << endl; cout << "Standard Deviation of the wait time list: " << stndrdDev << endl; cout << "===============================================" << endl << endl; } string getBankName(ifstream &inputFile, string &fileName) { string bankName; inputFile.open(fileName.c_str()); inputFile >> bankName; return bankName; }
