blocks|key|1151296|text|在习惯了C#中的var关键字之后，我开始在C%2B%2B11中使用auto关键字。它们都是通过推断来确定类型的，当你只是想让编译器为你找出类型时，它们都很有用。下面是你的代码的C%2B%2B11端口：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1151297|#include+<array>

After getting used to the <code>var</code> keyword in C#, I'm starting to use the <code>auto</code> keyword in C++11. They both determine type by inference and are useful when you just want the compiler to figure out the type for you. Here's the C++11 port of your code:

<pre><code>#include &lt;array&gt;
#include &lt;string&gt;

using namespace std;

array&lt;string, 3&gt; strarr = {"ram", "mohan", "sita"};
for(auto str: strarr) {
 listbox.items.add(str);
}

Although doing a simple loop is recommended :-)

blocks|key|1151085|text|类似于：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1151086|const+char*+strarr+=+{"ram","mohan","sita",+0L};

for(int+i+=+0;+strarr[i];+%2B%2Bi)

}|code-block|syntax|javascript|1151087|也适用于标准C。不确定在C%2B%2B中如何在没有空元素的情况下检测strarr的结尾，但上面的方法应该可以工作。|1151088|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Something like:

<pre><code>const char* strarr = {"ram","mohan","sita", 0L};

for(int i = 0; strarr[i]; ++i)
{
 listbox.items.add(strarr[i]);

Also works for standard C. Not sure in C++ how to detect the end of the strarr without having a null element, but the above should work.
