Introduction to Structures
What is a Structure?
A structure is something that supports an object or a load.
Requirements of a Structure
A structure must:
- Be strong enough to support its own weight and any load that is put on it.
- Be stable (not topple over easily when a force acts on it).
- Resist deformation without losing its shape more than expected.
Types of Structures
There are three types of structures:
- Mass Structures: Solid structures that rely on their own weight to resist loads. Examples include Roman bridges, aqueducts, walls,

C++ Programming Fundamentals: Arrays, References, Structures, and More
Arrays can only contain the same data type. Data types: bool, char, int, float, double. To declare an array: type arrayName [ arraySize ]; — This is called a single-dimension array. To declare a 10-element array called balance of type double, use this statement:
Double balance[10];
—
You can initialize C++ array elements either one by one or using a single statement:
Double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0};
— Or you can do this this way:
Double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0}

Motherboard
The motherboard, also known as the mainboard or system board, is the central printed circuit board in computers and other systems. It connects and facilitates communication between crucial electronic components, including the central processing unit (CPU), memory, and peripherals.
Microprocessor (CPU)
The microprocessor is the brain of a computer, incorporating the functions of the central processing unit on a single integrated circuit. It accepts digital
