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...
In this example, the Student struct contains three fields: name, age, and gpa. Now that we have our struct defined, let’s explore how to initialize an array of structs. Method 1: Static Initialization One of the simplest ways to initialize an array of structs is through static initializati...

The routines can use this parameter to access private data that the driver has associated with the lookaside list. For example, the driver might allocate an instance of the following structure to collect private data for each lookaside list that it creates: C++ Copy typedef struct { ULONG ...
