C++ Outputing Formats:

I'm having a difficult time changing my codes from C to C++.

For C:

Code:

---

printf("%2d/%-2d ", month, day);

printf("%02d:%02d ", hour, minute);

printf("%-15s %s\n", subject, location);

---

How do you convert the C codes into C++ with the same outputting format?

Thanks

Code:

---

#include <iostream>
#include <iomanip>

int main()
{
  std::cout << std::setw(2) << month << '/' << std::left << std::setw(2) << day;
  std::cout << std::setw(2) << std::setfill('0') << hour << ':' << std::setw(2) << minute;
  std::cout << std::setfill(' ');
  std::cout << std::left << std::setw(15) << subject << ' ' << location;
}

This is what I did:

Code:

---

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
..
    cout << setw(2) << day.month << "/" << left << setw(2) << day.day << endl;
    cout << setw(2) << time.hour << ":" << setw(2) << time.minute << endl;
    cout << setw(16) << left << appt->subject << appt->location << endl;
...
}

Still not the same format? Any ideas?

Should be it - explain what's missing.

This is my output when I convert it to C++:

Start End Subject Location
9: 010:30Team CAFE CA
11:0 12:30Team CAFE NY
13:0 18:0 CAFE CAFE TX


This is what it should look like:

Start End Subject Location
09:00 10:30 Team CAFE CA
11:00 12:30 Team CAFE NY
13:00 18:00 CAFE CAFE TX

*** Ignore the top. Below is the correct format.

This is my output when I convert it to C++:

Start End Subject Location
9: 010:30Team CAFE CA
11:0 12:30Team CAFE NY
13:0 18:0 CAFE CAFE TX


This is what it should look like:

Start End Subject Location
09:00 10:30 Team CAFE CA
11:00 12:30 Team CAFE NY
13:00 18:00 CAFE CAFE TX

Well I notice you aren't using setfill, and you have to. I showed you how in my example.

Thanks. That does solve the problem.

Another quick question:

I have

Code:

---

cout << "Start  End            Subject      Location";

---

as my first line, but how do I get it to be the same spacing as the day/month , hour/minute , subject and location?

Perhaps if you used the same values for setw for the same columns?

You might want to consider the use of Boost.Format.

One way is to decide on the field widths and set them accordingly for the headers too.
