Study Notes

Structure in C++ Programming

A structure is a collection of variables of different data types that are stored together in memory, allowing for efficient use of memory and simplified programming.

Purpose of Using a Structure

The primary purpose of using a structure is to organize and group related variables together, making it easier to manipulate and access the data.
Structures enable the creation of complex data types, allowing for a more efficient and organized representation of real-world objects and scenarios.

Defining a Structure Variable

A structure variable is defined using the struct keyword, followed by the structure name and the variables it contains, enclosed in curly braces {}.
The structure definition is typically followed by a semicolon ;.

Accessing Structure Members

Members of a structure variable are accessed using the dot notation, where the structure variable name is followed by a dot . and the member variable name.
For example, structVariable.memberVariable would access the memberVariable within the structVariable.

Memory Allocation for a Structure Variable

Memory allocation for a structure variable occurs when the structure is defined, and the compiler reserves a contiguous block of memory to store all the member variables.
The memory size allocated is equivalent to the sum of the sizes of all the member variables.
