Zero and setprecision

[danielmtnz]

I have a program that needs to output the input with a setprecision of 2 but when it outputs 0, it has to be "0", not "0.00"

How will I go about that?

Here is my code:

void PrintAllSales(double sales[][SLSPRDT])
{
    cout << fixed << showpoint << setprecision(2) << endl;
    
    cout << "ALL SALES \n";
    WriteLine('=', 63);
    cout << "Product #" << setw(6) << "|" << setw(15) << "1 " << "|" << setw(15) << "2 " << "|"
         << setw(15) << "3 " << "| \n";
    WriteLine('-', 63);
    
    for(int i = 0; i < SLSPRNS; i++)
    {
        cout << "Salesperson " << i+1 << " |";
        for(int j = 0; j < SLSPRDT; j++)
        {
            cout << setw(14) << sales[i][j] << " |";
        }
        cout << endl;
    }
}

And here is how it comes out:

1 2 3 4

ALL SALES =============================================================== Product # | 1 | 2 | 3 |

Salesperson 1 | 2000.00 | 0.00 | 299.00 | Salesperson 2 | 0.00 | 2543.98 | 95.99 | Salesperson 3 | 0.00 | 0.00 | 19.99 | Salesperson 4 | 0.00 | 3854.75 | 0.00 |

But it should be like this:

1 2 3 4

ALL SALES =============================================================== Product # | 1 | 2 | 3 |

Salesperson 1 | 2000.00 | 0 | 299.00 | Salesperson 2 | 0 | 2543.98 | 95.99 | Salesperson 3 | 0 | 0 | 19.99 | Salesperson 4 | 0 | 3854.75 | 0 |

Any help would be appreciate it.

you can use if statements to check if there is a number that is not zero, set the decimal places to two, else just print 0

Where would I do that? Because I tried that but it doesn't seem to work. Any other ideas?

void PrintAllSales(double sales[][SLSPRDT])
{
    cout << fixed << showpoint << setprecision(2) << endl;
    
    cout << "ALL SALES \n";
    WriteLine('=', 63);
    cout << "Product #" << setw(6) << "|" << setw(15) << "1 " << "|" << setw(15) << "2 " << "|"
         << setw(15) << "3 " << "| \n";
    WriteLine('-', 63);
    
    for(int i = 0; i < SLSPRNS; i++)
    {
        cout << "Salesperson " << i+1 << " |";
        for(int j = 0; j < SLSPRDT; j++)
        {
            if(sales[i][j] != 0)
            {
                setprecision(0);
            }
            else
            {
                setprecision(2);
            }
            cout << setw(14) << sales[i][j] << " |";
        }
        cout << endl;
    }
}

any other ideas?

set the precision if it is not zero. otherwise just directly output '0'

[danielmtnz]

Can you show me some code of what you mean because I'm trying that but since it is an array I don't see how I can output just '0' if everything else would be setprecision of 2.

void PrintAllSales(double sales[][SLSPRDT])
{    
    cout << "ALL SALES \n";
    WriteLine('=', 63);
    cout << "Product #" << setw(6) << "|" << setw(15) << "1 " << "|" << setw(15) << "2 " << "|"
         << setw(15) << "3 " << "| \n";
    WriteLine('-', 63);
    
    for(int i = 0; i < SLSPRNS; i++)
    {
        cout << "Salesperson " << i+1 << " |";
        for(int j = 0; j < SLSPRDT; j++)
        {
            if(sales[i][j] != 0)
            {
                cout << fixed << showpoint << setprecision(2);
            }
            else
            {
                cout << '0';
            }
            cout << setw(14) << sales[i][j] << " |";
        }
        cout << endl;
    }
}

And this is what I get:

1 2 3 4

Product # | 1 | 2 | 3 |

Salesperson 1 | 1.00 |0 0.00 | 2.00 | Salesperson 2 | 1.00 | 2.00 | 3.00 | Salesperson 3 | 1.00 | 2.00 | 3.00 | Salesperson 4 | 1.00 | 2.00 | 3.00 |

[Michaela Elise]

 for(int i = 0; i < SLSPRNS; i++)
    {
        cout << "Salesperson " << i+1 << " |";
        for(int j = 0; j < SLSPRDT; j++)
        {
          if(sales[i][j] != 0)
            {
                cout << fixed << showpoint << setprecision(2) << setw(14) << sales[i][j] << " |";
            }
            else
            {
                cout <<  setprecision(0) << setw(14) <<  '0'  << " |";
            }
        }
        cout << endl;
    }

maybe that.

[danielmtnz]

That did it. The trick was to cout the array inside the if statement, I see now.

Thank you.

You are welcome :)
