问题描述
这种语法不起作用
nl,nt,ns = 0;
唯一得到初始化的是ns。
nl和nt因为他们没有初始化似乎从
内存得到一些垃圾。
我做了这两个版本的工作:
nl = 0; nt = 0; ns = 0;
nl = nt = ns = 0;
我想知道它的正常工作方式是什么?在下面的上下文我
想知道逗号是如何被解释为:
nl,nt,ns = 0;
谢谢任何见解。
只是好奇:为什么这很重要?如果你需要数百万个变量,
只需要make和array,并用循环初始化它。或者使用calloc(),
,它的工作方式类似于malloc(),但是将缩写初始化为0.

$ b第3行
$ b,make之间和阵列是一个校对的理由,而不是
相信一个拼写检查器。

This syntax does not to work
nl, nt, ns = 0;
The only one that get''s initialized is ns.
nl and nt because they don''t initialize seem to get some junk from
memory.
I have done these two versions that work:
nl = 0; nt = 0; ns = 0;
nl = nt = ns = 0;
I wonder what is the normal way it is done? In the context below I
wonder how the commas are interpreted as:
nl, nt, ns = 0;
Thanks for any insight.
Just curious: why does it matter? If you need millions of variables,
just make and array, and initialize it with a loop. or use calloc(),
which works like malloc(), but initializes the condense to 0.

on line 3, between "make" and "array" is a reason to proofread, and not
trust a spell checker.
