In C, structures allow you to group together variables of different data types under a single name. It's like creating a custom data type. Here's a simple explanation with an example:
#include <stdio.h>
// Define a structure named 'Person'
struct Person {
char name[50];
int age;
float height;
};
int main() {
// Declare a variable of type 'Person'
struct Person person1;
// Assign values to the members of 'person1'
strcpy(person1.name, "John");
person1.age = 30;
person1.height = 6.0;
// Access and print the values
printf("Name: %s\n", person1.name);
printf("Age: %d\n", person1.age);
printf("Height: %.2f\n", person1.height);
return 0;
}
In this example
Person using the struct keyword. Inside the structure, we specify members (variables) such as name, age, and height, each with its own data type.main() function, we declare a variable person1 of type Person. This variable can hold all the members defined in the Person structure.person1 using the dot (.) operator. For example, person1.name refers to the name member of the person1 structure, and we use strcpy() to copy the string "John" into it..) operator again.When you run this program, it will print:
Name: John
Age: 30
Height: 6.00
This demonstrates the use of structures in C to group related data together under a single name.
