atoi()与其他语言 [英] atoi() with other languages

问题描述

我正在从事国际化项目.除0-9外，其他语言(例如阿拉伯语或中文)是否对数字使用不同的表示形式?如果是这样，是否存在可以解释这些其他表示形式的atoi()版本?

我应该补充一点，我主要关心的是分析用户的输入.如果用户输入其他表示形式，则我想确保将其识别为数字并相应地进行处理.

解决方案

我可以使用std::wistringstream和语言环境生成此整数.

#include <sstream>
#include <locale>
using namespace std;

int main()
{
  locale mylocale("en-EN"); // Construct locale object with the user's default preferences
  wistringstream wss(L"1");  // your number string
  wss.imbue( mylocale );    // Imbue that locale
  int target_int = 0;
  wss >> target_int;
  return 0;
}

有关流类的详细信息和关于语言环境类. /p>

I am working on a internationalization project. Do other languages, such as Arabic or Chinese, use different representations for digits besides 0-9? If so, are there versions of atoi() that will account for these other representations?

I should add that I am mainly concerned with parsing input from the user. If the users types in some other representation I want to be sure that I recognize it as a number and treat it accordingly.

解决方案

I may use std::wistringstream and locale to generate this integer.

#include <sstream>
#include <locale>
using namespace std;

int main()
{
  locale mylocale("en-EN"); // Construct locale object with the user's default preferences
  wistringstream wss(L"1");  // your number string
  wss.imbue( mylocale );    // Imbue that locale
  int target_int = 0;
  wss >> target_int;
  return 0;
}
