in the program im writing, i was going to output this using cout :
cout << left << setw(10) << newAccount.getN umber() << setw(18)
<< newAccount.getN ame() << setw(18) << newAccount.getF amName() <<
setw(11)
<< setprecision(2) << right << fixed << showpoint<<
newAccount.getB alance() << endl;
my question is, i want to declare a string , say result, and let result be
equal to the above output;
is there a way to format a string using left, setw or similar functions?
i know the following wont work, but (thats actually what i need to do ) :
string result;
result = left << setw(10) << newAccount.getN umber() << setw(18)
<< newAccount.getN ame() << setw(18) << newAccount.getF amName() <<
setw(11)
<< setprecision(2) << right << fixed << showpoint<<
newAccount.getB alance() << endl;

Read about, and use, 'ostringstream' .

Create an 'ostringstream' object (this type is declared by the
standard header <sstream>). Apply the same operations to the
ostringstream object that you would have to e.g. 'cout'. When done,
the ostringstream's 'str()' member function will (barring any
errors writing to the ostringstream) return a 'std::string'
(this type is declared by standard header <string>) containing the
formatted data.
#include <iomanip>
#include <iostream>
#include <sstream>
#include <string>
int main()
{
std::ostringstr eam oss;
for (int i = 7; i < 15; ++i)
oss << std::setw(3) << i << '\n';
std::string output(oss.str( ));
std::cout << output << '\n';
return 0;
}

Hello, all! I have question about String.Format method.
There are two variants: public static string Format(string, params
object); and public static string Format(IFormatProvider, string, params
object);
What happens if i will use String.Format("{0} and {1}", "one", "two")
instead of String.Format(System.Globalization.CultureInfo.CurrentCulture,
"{0} and {1}", "one", "two")?

I am looking for a VBA "format" or "template" function, that is,
a function that takes a format string and a varying number of

would return the string

I'm having trouble the string.Format() throwing exceptions and I can't figure
out what I am doing wrong.
Given the following setup code:
string str = { "one", "two", "three", "four" };
double val = { 1.0, 2.0, 3.0, 4.0 };
string fmt = "{0} {1} {2} {3}";
The following variations of string.Format() will work just fine with strings:
string s1 = String.Format(fmt, str, str, str, str); // works

Hi
Could somebody please explain what the following line of code means
String.Format("{0}\{1}.{2:00}", C:\, myfile.txt, 1
It's actually the first argument that I don't understand. What is the purpose of "{0}\{1}.{2:00}"? I've been using VB .NET for a year now, and have never come across anything like this

the problem is like this.
i want to print a line like this:
