I need someone to help me correct these last few errors in code. The outputs for files 1 and 6 at the bottom of the code give me a double output for the last set of numbers. someone please help me fix this and explain what in the code is wrong

First i will post the code, then the answers i get for the outputs.

#include #include #include #include #include using namespace std;

double calculateFutureValue(double presentValue, double interestRate, int months){ double futureValue = (double)presentValue * pow( (1 + interestRate), months); return futureValue;}

unsigned int readfile(ifstream& inF, double& presentValue, double& interestRate, int& months){ inF >> presentValue; inF >> interestRate; inF >> months; if(presentValue <= 0 || interestRate <= 0 || months <= 0){ return 2;} else if( !(presentValue <= 0 || interestRate <= 0 || months <= 0)) return 1;

if(inF.eof()) return 0; }

void write2File(ofstream &of, double futureValue, double presentValue, double interestRate, int months) { of << futureValue << "\t" << presentValue << "\t" << interestRate << "\t" << months << " "; } // main function int main(void) { string infile; cin >> infile; ifstream inF; inF.open(infile.c_str()); if(!inF) { cout << "File \"" << infile << "\" could not be opened" <

if(returnVal == 2){ cout << setprecision(2) << fixed << showpoint; cout << presentValue << " " << interestRate << " " << months << endl; cout << "One or more of the above values are not greater than zero" << endl; if (presentValue == 0 && interestRate == 0 && months == 0){ return(0); } }

else if(returnVal == 1) { futureValue = calculateFutureValue(presentValue, interestRate/100, months); write2File(of, futureValue, presentValue, interestRate, months); } } inF.close(); of.close(); return (0); }

NUMBERS 1 AND 6 HAVE THE LAST OUTPUT PRINTED TWICE THIS IS WHAT I NEED HELP WITH.

1: Compare output keyboard_arrow_up 0 / 10

Input

input2.txt

Your output

Future Value Present Value Monthly Interest Months

12205.06 10000.00 0.42 48

12205.06 10000.00 0.42 48 (double output here as well)

Expected output

Future Value Present Value Monthly Interest Months

12205.06 10000.00 0.42 48

2: Compare output keyboard_arrow_up

10 / 10

Input

input3.txt

Your output

-10000.00 1.10 48 One or more of the above values are not greater than zero 10000.00 -1.00 12 One or more of the above values are not greater than zero 10000.00 1.10 0 One or more of the above values are not greater than zero 0.00 0.00 0 One or more of the above values are not greater than zero

3: Unit test keyboard_arrow_up

5 / 5

Call to calculateFutureValue # 1

Test feedback

The call to calculateFutureValue returned the correct value

4: Unit test keyboard_arrow_up

5 / 5

Call to calculateFutureValue # 2

Test feedback

The call to calculateFutureValue returned the correct value

5: Unit test keyboard_arrow_up

5 / 5

Call to calculateFutureValue # 3

Test feedback

The call to calculateFutureValue returned the correct value

6: Compare output keyboard_arrow_up

0 / 10

Input

input4.txt (wrong output plese help to fix double output at end.

Your output

Future Value Present Value Monthly Interest Months

76079.56 45000.00 1.10 48

76079.56 45000.00 1.10 48 (this double output is what messes up the code

Expected output

Future Value Present Value Monthly Interest Months 5458.19 3000.00 0.50 120 35.95 1.00 1.00 360 76079.56 45000.00 1.10 48

One or more of the above values are not greater than zero

Expected output

This test case should produce no output
