How do I create a string of blanks in C++?

Question

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!

Answer 1

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.

Answer 2

#include <string>
std::string mystring(5,' ');

Answer 3

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

Answer 4

5 spaces to standard output:

std::cout << std::string( 5, ' ' ) << std::endl;
