format string

[Someonekicked]

in the program im writing, i was going to output this using cout :
cout << left << setw(10) << newAccount.getNumber() << setw(18)
<< newAccount.getName() << setw(18) << newAccount.getFamName() <<
setw(11)
<< setprecision(2) << right << fixed << showpoint<<
newAccount.getBalance() << 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.getNumber() << setw(18)
<< newAccount.getName() << setw(18) << newAccount.getFamName() <<
setw(11)
<< setprecision(2) << right << fixed << showpoint<<
newAccount.getBalance() << 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::ostringstream 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;
}
