Structures in C are user-defined data types that allow grouping variables of different types under a single name. This is particularly useful for organizing complex data. Here are some examples to illustrate the use of structures in C programming.
Basic Structure Example
To define a structure, use the struct keyword followed by the structure name and the members enclosed in curly braces. Here's an example of a simple structure to store student information:
#include <stdio.h>// Define a structure named StudentDatastruct StudentData {char *stu_name;int stu_id;int stu_age;};int main() {// Declare a variable of type StudentDatastruct StudentData student;// Assign values to the structure membersstudent.stu_name = "Steve";student.stu_id = 1234;student.stu_age = 30;// Print the values of the structure membersprintf("Student Name is: %s\n", student.stu_name);printf("Student Id is: %d\n", student.stu_id);printf("Student Age is: %d\n", student.stu_age);return 0;}Copied!âś•CopyOutput:
