C++ formatting

[amolchopra]

Hi,

I have to display a string in a box in the following format:

Phase<SPACEEE>:
b<SPACEEEEEE>:
Di<SPACEEEEE>:
qi<SPACEEEEEE>:
Forecast ended by :

Thus everthing should be neatly arranged according to the length of the biggest string in this group which is Forcast ended by.

I hope I could explain the problem clearly.

How can I format the string beautifully?

Thanks.

Regards,

Amol

In C++, the iostreams have methods and functions that control the formatting of strings and numbers. Play around with the following and you should be able to get the formatting you want.

std::cout << std::left  << std::setw( 10) << "hello" << "--" << std::endl

There is also std::right and std::setfill( char). Some of these functions have a short life(i.e. setw) and some stay until reset (i.e. left)

Dude,

Thanks. But I am using MFC and I have to format the string using CString.Format().

So, it happens to look something like this:

strAnnotation.Format("Phase:%s\r:%1.1e\rDi:%1.1e(p er day)\rQi:%7.2f(m^3/day)\rTi:%s\rTcutof, value1, value2, value3, value4, value5)

Any ideas??

Those format statements look suspicously like C style format statements. Try changing the %s to %15s or %-15s. That will justify and set the width of that string. If you want the numeric 15 to be a variable, you'll have to consult the doc for Format.
