在C我试图在两种不同的方式分配刺痛变量

In C I tried to assign a sting to variable in two different ways

char question[200]; strcpy( question, "This is the question" );

和

char question[] = "This is the question";

和这两个作品...但什么是这两种方法之间的区别？

and both works... but what's the difference between these two methods?

推荐答案

，这种差异可能的灵活性。这

The difference is probably flexibility. This

strcpy( question, "This is the question" );

在声明变量之后，你可以做任何时候。而这样的：

you can do anytime after you declare the variable. Whereas this:

char question[] = "This is the question";

您必须在申报时直接使用。

You have to use directly during declaration time.

在第二例如问题的长度得到固定长度对于空终止文本+1。你不能改变这个变量的长度后，所以你不能分配较大字符串，它的例子。

In the second example the length of question got fixed to length of text +1 for null terminator. You can't change length of this variable later, so you can't assign larger string to it for example.
