Creating Your First Struct

Using the visual cue at the end of first chapter , let's create a data type to describe a chemical element:

Note
The mass and sequence number cannot be negative, so it would be more efficient to use the unsigned short int data type.

Now, we can “create” a chemical element:

The code will look like this:

Access to struct fields will be discussed in the next chapter.

Try to describe the geometric point A with a structure.

Task

Create a structure named Point;
Create a field for the name of the future point;
Create fields for the X and Y coordinates.

Task

Create a structure named Point;
Create a field for the name of the future point;
Create fields for the X and Y coordinates.
