Hi,

I dont see any issues with code. it is working. Issue must be with your debuggin settings in IDE. To get ride of this issue you may stop your debug settings.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <cmath>
using namespace std;
//Reads the inputs principal amount, rate of interest, and number of payments.
void readInputs(double &presentValue, double &rateOfInterest, int &numOfPayments, double &tax_pm)
{
cout << "Enter the loan amount: ";
cin >> presentValue;
cout << "Enter the yearly rate of interest(as a percentage): ";
cin >> rateOfInterest;
rateOfInterest = (rateOfInterest / 100) / 12;
cout << "Enter the number of payments (in months): ";
cin >> numOfPayments;
cout << "What is the tax amount per year? $";
cin >> tax_pm;
}
//Calculates the EMI per payment, given the inputs.
void EMICalc(double presentValue, double rateOfInterest, int numOfPayments, double &EMI)
{
EMI = (rateOfInterest * presentValue) / (1 - pow((1 + rateOfInterest), (-1 * numOfPayments)));
EMI = floor(EMI * 100 + 0.5) / 100;
}

double totalTax = tax * No_of_Payments_in_years;
double tax_pm = totalTax / numOfPayments;
}
void printTable(double pV, double roI, int noP, double emi, double tax, double tax_pm)
{

double interest, principal;
for (int i = 0; i < noP; i++)
{

if (interest < 0)
{

}
principal = emi - interest;
if (principal < 0)
{

}

}

outFile << setw(10) << fixed << setprecision(2) << "$" << principal << setw(10) << fixed << setprecision(2) << "$" << interest;

}
outFile << "Final Payment " << interest + principal << endl;
}
int main()
{
double presentValue, rateOfInterest, EMI, tax, tax_pm;
int numOfPayments;

EMICalc(presentValue, rateOfInterest, numOfPayments, EMI);

cout << "The monthly EMI is: " << EMI << endl;
double totalInterest = EMI * numOfPayments - presentValue;
cout << "Total interest paid: " << totalInterest << endl;
}

Output:

sh-4.2$ g++ -o main *.cpp

sh-4.2$ main

Enter the loan amount: 10000

Enter the yearly rate of interest(as a percentage): 10

Enter the number of payments (in months): 12

What is the tax amount per year? $100

The monthly EMI is: 879.16

Total interest paid: 549.92
