Structures in C++
Structures are an essential part of C++ programming, offering a powerful way to group related data members together under a single user-defined data type. They provide a foundation for creating more complex data structures and are commonly used in various programming scenarios.
In C++, a structure is a composite data type that allows you to group variables of different data types together. Unlike arrays, which store elements of the same data type, structures can hold a combination of variables of various types. This flexibility makes structures ideal for representing real-world entities with multiple attributes.
In the below PDF we discuss about Structures in C++ in detail in simple language, Hope this will help in better understanding.
The basic syntax of defining a structure in C++ is as follows:
struct StructureName {
DataType member1;
DataType member2;
// Additional members...
};StructureName is the name of the structure.
DataType represents the data type of each member variable.
member1, member2, and so on are the variables or attributes that constitute the structure.
Creating and Using Structures:
Once you’ve defined a structure, you can declare variables of that structure type, just like you would with any other data type. Here’s an example:
struct Person {
std::string name;
int age;
double height;
};
int main() {
// Declare a variable of type Person
Person person1;
// Initialize the members
person1.name = "Alice";
person1.age = 30;
person1.height = 5.8;
// Accessing structure members
std::cout << "Name: " << person1.name << std::endl;
std::cout << "Age: " << person1.age << std::endl;
std::cout << "Height: " << person1.height << " feet" << std::endl;
return 0;
}
In this example, we’ve created a Person structure with three members: name, age, and height. We then declare a variable person1 of type Person, initialize its members, and print them to the console

A structure in C++ is a user-defined data type that groups together variables of different data types under a single name. It allows you to create a composite data type to represent real-world entities.
You declare a structure using the struct keyword followed by the structure name.
The members of a structure are the individual variables or data elements contained within the structure. In the example above, rollNumber, name, and marks are the members of the Student structure.
You can access structure members using the dot (.) operator.
The members of a structure are the individual variables or data elements contained within the structure. In the example above, rollNumber, name, and marks are the members of the Student structure.
How do you access members of a structure in C++?
