Compound literals provide a concise way to initialize struct variables with specific values. Structs are commonly used in C to represent complex data structures, such as linked lists, trees, and graphs. 使用复合字面量是另一种初始化结构体的方法,其中您创建一个临时对象,以结构体字面量的形式,然后...
name x={3,"char",...}; 3. initialize an array of struct: name arr[]={ {1,"xy",...}, {2,"ab",...}, ... }; The code fragment below demonstrates how to initialize an array of structures within a Microsoft C program. Each element is grouped within brackets, and the elements...
(原創) 如何对array或struct做初始化? (memset()) (C/C++) (C) 当宣告C/C++的built-in type后,必须马上initialize该变量的值,因为C/C++在宣告变量时,仅为该变量配置了一块内存,却没对该变量设定任何初始值,所以该变量目前的值为宣告该变量前所残留的值,虽可直接使用该变量,但并没有任何意义。 尤其在使用...
这段话很长很绕,简单的说,如果aggregate(这里简单理解为struct,准确的 表述去看标准)的某个元素是aggregate,就按照普通的aggregate初始化规则找 到该aggregate的初始化列表开始的地方,如果是大括号扩着的,就用那个括 号里面的list初始化这个aggregate,否则就从这里开始找到"足够"的条目给 自己来initialize,剩下的给别...

I have a question related to struct initialization in C. I have a struct: struct TestStruct { u8 status; u8 flag1; u8 flag2; }; I want a generic function/macro to initialize this struct and set the value of one parameter, eg status =1, easy way is: TestStruct t = {}; t.sta...

Asked7 years, 4 months ago Modified7 years, 4 months ago Viewed2k times I'm aiming to implement an algorithm to check if a graph is topologic. But well, that's not the issue here. I'm getting a core dump when trying to initialize my graph structure with the given data. ...
