Adding a scoll list


I am adding to the program a scoll list (12 lines at a time).   I can not get the program to run.  Please help.  Thank you
#include <iomanip>
  #include <math.h>
  #include <string>
  #include <iostream>
  #include <stdlib.h>

//Start of program
  using namespace std;
  int main(void)
  {
 
// Set up required variables  
    double  loanAmount; // loan amount                      
    int Years;          // Years of loan                      
    int term;           // Loan term
    int month = 12;     // 1 year = 12 months
    double  IntRate;    // Interest rate                    
    double MonthRate;   // Months of loans
    double MonthTerm;   // Term of loan
     char choice;

     while (true)
     {
//Infomation need for Monthly Mortgage Payment

           cout << "Enter the loan amount in dollars: ";
           cin >> loanAmount;
   
           cout << "Enter the loan term in years: ";
           cin >> Years;
   
           cout << "Enter the interest rate: ";
           cin >> IntRate;

// Calculate Monthly Mortgage Payment
   
          MonthTerm = Years * 12;          
          MonthRate = IntRate / (12 * 100);
 
          double PowCalc = pow(1+MonthRate,MonthTerm);
          double paymentAmount = ((MonthRate*PowCalc) / (PowCalc-1)) * loanAmount;

         cout << fixed << showpoint;            //Decimal Function
         cout << setprecision(2);              //Set Number of Decimals places

//Information give on  Monthly Mortgage Payment
      system("cls");
      cout << endl;   //space
      cout << "Loan amount of $" << loanAmount << endl;
      cout << endl;   //space
      cout << "For a term of " << Years << " years" << " (" << Years*12 << " months)" << endl;
      cout << endl;   //space
      cout << "With an interest rate of " << IntRate << "%" << endl;
      cout << endl;   //space
      cout << "Monthly mortgage payment of $" <<paymentAmount << " per month." << endl;
//Quit or Continues (Loop)  
       do
//Produce a listing for each month
      monthly_payment = amount;
      for (month=1; month<term_months + 1; month++)      
      {
//Information give on  Monthly Mortgage Payment
      system("cls");
      cout << endl;   //space
      cout << "Loan amount of $" << loanAmount << endl;
      cout << endl;   //space
      cout << "For a term of " << Years << " years" << " (" << Years*12 << " months)" << endl;
      cout << endl;   //space
      cout << "With an interest rate of " << IntRate << "%" << endl;
      cout << endl;   //space
      cout << "Monthly mortgage payment of $" <<paymentAmount << " per month." << endl;        
     
// pause output every twelve lines, except for the final output
         if (month % 21 == 0 && month % term_months != 0)
               {  
                    system("pause");
                    system("cls");
         }// end if
      }// end for

     cout << "Would you like to perform another calculation? ";
     cin >> choice;
    } while (choice == 'Y' || choice == 'y');
    return 0;

Hi Shannon3077.
>>I can not get the program to run.
Infortunately, there are a lot of errors, see below:

1.

   while (true)
   {
//Infomation need for Monthly Mortgage Payment

change on:

  do
  {

and remove unneeded "do" from:

//Quit or Continues (Loop)  
    do

2. Remove:

//Produce a listing for each month
     monthly_payment = amount;

and rename variable month :

 int month = 12;   // 1 year = 12 months

on months:

 int months = 12;   // 1 year = 12 months

3.
Change your "for" cycle,

  for (month=1; month<term_months + 1; month++)    
     {
//Information give on  Monthly Mortgage Payment

according to changes you have made:

  for (int month=1; month<months + 1; month++)    
     {
//Information give on  Monthly Mortgage Payment

4. Rename variable "term_months" on "months" (they have same values, and meaning).

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

then you have to remove

while (choice == 'Y' || choice == 'y');

No :)
i propose to change line

while (true)
  {
//Infomation need for Monthly Mortgage Payment

on:

 do
 {

then second "do" became unneeded.
