is this correct

char teststr[100]="\0";

or is there another method to initialise;

char teststr [100] =""足够了，因为字符串文字在结尾处已经有一个

NUL字符（在这种情况下位于0）。

char teststr[100] = "" suffices, because the string literal already has a
NUL character at the end (in position 0, in this case).

你好

它有效。

还是有其他方法可以初始化;

hi
is this correct

char teststr[100]="\0";
It works.
or is there another method to initialise;

以下两者做同样的事情，或许更优雅的触摸：

char teststr [100] ="" ;;

char teststr [100] = {0 };

The following both do the same thing, perhaps a touch more elegantly:

char teststr[100] = "";
char teststr[100] = {0};

它的工作原理。

hi

char teststr[100]="\0";
It works.

或者是否有另一种初始化方法;

or is there another method to initialise;

以下两者都做同样的事情，也许是更优雅的触摸：

char teststr [100] =" " ;;

The following both do the same thing, perhaps a touch more elegantly:

char teststr[100] = "";

这会将第一个元素初始化为终止空字符，并且
对数组的其余部分不执行任何操作。 char teststr [100] = {0};

This initializes the first element to a terminating null character and
does nothing to the rest of the array. char teststr[100] = {0};

这个不做同样的事情。这个将整个

数组初始化为零。

This one does not do the same thing. This one initializes the entire
array to zeros.
