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
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...
In C programming, a struct (short for "structure") is a user-defined data type that allows grouping variables of different data types under one name. Initializing a struct properly ensures that all its members have predictable values when used. There are several ways to initialize a struct in...
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...
(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。
