If you don't need to be backward-compatible with ANSI/MBCS builds, you could just drop the TCHAR thing, and just explicitly use wchar_t.In this case you may also directly use std::wstring instead of std::string:Копировать wstring z = L"abc"; const wchar_t * psz = ...
Method-1 std::stoi(str); // str is your number as std::string. C++11 need. 1. 2. Method-2 string a = "25"; int 1. 2. Method-3 std::istringstream 1. 参考 Convert string to int C++ [duplicate]
constexprintmaxdigits = std::numeric_limits<int>::digits10; So you first have to cut string to size before you release a convert function on the CString object. A CString handles in UNICODE mode wchar_t characters, so you need something like _wtoi() to do the conversion. ...

Suppose you have a constant floating-point number, and you want to convert it into a string using preprocessor macros. Here’s how you can do it: #include <iostream> #include <string> using std::cout; using std::endl; using std::string; #define STRINGIFY_FLOAT(x) #x int main() {...
The above code doesn't skip whitespaces before the "nan" string. If that is desired (because number parsing functions generally ignore leading spaces), it would be easy to add that to the code too: 1 2 3 4 5 6 inlinedoublemy_atof(constchar*str) {while((*str) && isspace(*str)) ...
