You can access the members of the structure using the dot operator (.). The general syntax is:

structureVariable.memberName

Here’s how you can assign values to the members of the person1 variable and then access them:

#include <stdio.h>
#include <string.h>

struct Person {
    char name[50];
    int age;
    float height;
};

int main() {
    struct Person person1;

    // Assigning values to person1's members
    strcpy(person1.name, "John Doe");
    person1.age = 30;
    person1.height = 5.9;

    // Accessing and printing the values of person1's members
    printf("Name: %s\n", person1.name);
    printf("Age: %d\n", person1.age);
    printf("Height: %.1f\n", person1.height);

    return 0;
}

person1.name accesses the name member of person1, person1.age accesses the age member, person1.height accesses the height member.
