I need to create a string of blanks in c++, where the number of spaces is a variable, so I can't just type it in. How do I do this without looping ?
Thanks!

size_t size = 5; // size_t is similar to unsigned int ‡ std::string blanks(size, ' '); See: http://www.cplusplus.com/reference/string/string/string/
‡ See the question on size_t if this isn't clear.

What if I want to pass the number of spaces as a parameter

5 can be replaced by a variable.

I wouldn't refer to the foot-note using
* - it looks like a pointer ;)

@Georg Fritzsche, I changed it to a double dagger, but there's not much I can do without being able to superscript it :(

Why is this answer upvoted more often compared to the one provided by cape1232? His way looks more clean to me.
#include <string> std::string mystring(5,' ');

#include <string> ..... //i is your variable length string s_blanks_length_i( i, ' ' );

5 spaces to standard output:
std::cout << std::string( 5, ' ' ) << std::endl;
