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...
Another effective way to initialize an array of structs is by using a function. This method encapsulates the initialization logic, making your code cleaner and more modular. Here’s how you can implement this: #include <stdio.h> struct Student { char name[50]; int age; float gpa; }; voi...
Here, we are usingdesignated initializerto initialize a structure. C language code to understand how we can initialize a structure? #include <stdio.h>// Creating a Student named structuretypedefstructStudent {// name and roll_no are its membercharname[20];introllno; } Student;intmain() {/...
