Cout control

I'm working at the Exercises at the end of chapter 4 of my old C++ instruction book, and the first one which has the out put of ints be limited to 10 columns and lines seemed easy untill I tried to have the numbers line up right. I need to find out the right way to control the output so short and long numbers line up right.
Is there some instructions on that?

You could use if() statements to find out how much space they need:

Code:

---

if(number < 10)
        cout << "    " << number;
else if(number < 100)
        cout << "  " << number;
else if(number < 1000)
        cout << "  " << number;
else if(number < 10000)
        cout << " " << number;

If you're using decimals then my method may not work too well lol. Good luck soldier!

Try out std::setw().

Example code:

Code:

---

#include <iostream>
#include <iomanip>

int main()
{
        unsigned int num1 = 51234511;
        unsigned int num2 = 12;

        std::cout << std::setw(10) << num1 << std::endl << std::setw(10) << num2 << std::endl;
        std::cin.get();

        return 0;
}

---

My output:

Code:

---

  51234511
        12
