C++報錯error cannot deduce type of initializer list because initializer list was not found include

• 完整錯誤信息: error: cannot deduce type of initializer list because std::initializer_list was not found; include
  <initializer_list>
• 問題發現在list上, 如:

#include <iostream>

using namespace std;

int main(){

	for(auto k: {1, 2, 3})
		cout<< k<< " ";
		
	return 0;
}

• 解決方法很簡單，因爲這裏{1,2,3}用到了C++11的特性
• 不需要添加<initializer_list>到頭文件
• 故編譯的時候寫g++ -std=c++11 c文件即可
• 更方便的，讓其默認採用c++11特性的方法見此link
