如何分配一个C结构内嵌？ [英] How to assign a C struct inline?

问题描述

typedef struct {
    int hour;
    int min;
    int sec;
} counter_t;

和在code，我想初始化该结构的情况下，没有明确初始化每个成员变量。也就是说，我愿意做这样的事情：

And in the code, I'd like to initialize instances of this struct without explicitly initializing each member variable. That is, I'd like to do something like:

counter_t counter;
counter = {10,30,47}; //doesn't work

有关十时30分47秒

而不是

counter.hour = 10;
counter.min = 30;
counter.sec = 47;

不记得语法对于这一点，并没有马上找到一种方法，从谷歌搜索做到这一点。

Don't recall syntax for this, and didn't immediately find a way to do this from Googling.

谢谢！

推荐答案

初始化：

counter_t c = {10, 30, 47};

分配：

c = (counter_t){10, 30, 48};

后者被称为复合文字。

The latter is called a "compound literal".
