Structures and Unions

 Structures and Unions

Structures and unions are used to create user-defined data types that can hold different types of data. Structures group related data together, while unions allow multiple variables to share the same memory location.

#include <stdio.h>

struct Person {

    char name[50];

    int age;

    float height;

};

union Data {

    int intValue;

    float floatValue;

    char stringValue[20];

};

int main() {

    struct Person person;

    strcpy(person.name, "John");

    person.age = 25;

    person.height = 175.5;

    printf("Name: %s\n", person.name);

    printf("Age: %d\n", person.age);

    printf("Height: %.2f\n", person.height);

    union Data data;

    data.intValue = 10;

    printf("Integer Value: %d\n", data.intValue);

    data.floatValue = 3.14;

    printf("Float Value: %.2f\n", data.floatValue);

    strcpy(data.stringValue, "Hello");

    printf("String Value: %s\n", data.stringValue);

    return 0;

}
