What is the easiest way to convert from int
to equivalent string
in C++. I am aware of two methods. Is there any easier way?
(1)
C++11 introduces std::stoi (and variants for each numeric type) and std::to_string, the counterparts of the C atoi
and itoa
but expressed in term of std::string
.
#include
std::string s = std::to_string(42);
is therefore the shortest way I can think of. You can even omit naming the type, using the auto
keyword:
auto s = std::to_string(42);
Note: see [string.conversions] (21.5 in n3242)
