String of Spaces

[Puvendran]

Hi,

I am very much a newbie in c++ and would appreciate feedback on the
following.
Due to known bug with setw() iomanipulator such that it only works
against numeric output , I need to create strings of spaces of varying
sizes.

Is there a function to do this or any easy way to detrive ?

Thanking you in advance

#include <iostream>

int main()
{
std::cerr << "[" << std::string( 10, ' ' ) << "]\n";
}

Thanks for the feedback.

One thing I needed to be aware of was if you pass 0 for the length
program does not work as expected.
