Can I "undo" endl?-CodePudding

I am facing a problem while doing a chart. I would want to output the chart in a same row without changing the code and without making it horizontal.

The code is displayed below:

# include <iostream>
using namespace std;

class InterestCalculator
{
protected:
    float principal_amount = 320.8;
    float interest_rate = 60.7;
    float interest = interest_rate/100 * principal_amount; 
public:
    void printInterest()
    {
    cout<<"Principal Amount: RM "<<principal_amount<<endl;
    cout<<"Interest Rate(%): "<<interest_rate<<endl;
    cout<<"Interest: RM"<<interest<<endl;
    }
};

class LoanCalculator : public InterestCalculator
{
private:
    int loan_term;
    int month;
    float month_payment;
public:

void displayVariable()
{
    cout<<"Enter loan amount (RM): ";
    cin>>principal_amount;
    cout<<"\n\nEnter annual interest rate(%): ";
    cin>>interest_rate;
    interest_rate = interest_rate / 100;
    cout<<"\n\nEnter loan term in years: ";
    cin>>loan_term;
    month = loan_term*12;
    month_payment = (principal_amount*interest_rate   principal_amount) / month;
    cout<<endl<<endl;

}

 void outputStatistics()
 {
      cout<<"Month\tPayment(RM)\tPrincipal(RM)\tInterest(RM)\tBalance(RM)\n";
      for(int i = 1; i <=month; i  )
      {
          cout<<i<<endl;
      }

      for(int j = 0; j <=month; j  )
      {
          cout<<"\t"<<month_payment<<endl;
      }
 }
 };

 int main()
{
    LoanCalculator obj;
    obj.displayVariable();
    obj.outputStatistics();
    return 0;
}

And the output is:

Enter loan amount (RM): 120


Enter annual interest rate(%): 1.2


Enter loan term in years: 1


Month   Payment(RM)     Principal(RM)   Interest(RM)    Balance(RM)
1
2
3
4
5
6
7
8
9
10
11
12  
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12
    10.12

Process returned 0 (0x0)   execution time : 3.940 s
Press any key to continue.

The output that I want:

Enter loan amount (RM): 120


Enter annual interest rate(%): 1.2


Enter loan term in years: 1


Month   Payment(RM)     Principal(RM)   Interest(RM)    Balance(RM)
1       10.12
2       10.12
3       10.12
4       10.12
5       10.12
6       10.12
7       10.12
8       10.12
9       10.12
10      10.12
11      10.12
12      10.12

Process returned 0 (0x0)   execution time : 3.940 s
Press any key to continue.

So is there any solution to this problem? I've searched for other solutions at stackoverflow but did not found one.

CodePudding user response：

You don't need to undo endl you just need to reorganise your code so that you do things in the correct order in the first place, like this

void outputStatistics()
{
    cout<<"Month\tPayment(RM)\tPrincipal(RM)\tInterest(RM)\tBalance(RM)\n";
    for(int i = 1; i <=month; i  )
    {
        // output one row at a time
        cout<<i<<"\t"<<month_payment<<endl;
    }
}

This code outputs one row at a time, your code outputted one column first and the next column second.
