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:
struct chemicalElement
{
char name[3];
int atomicNum;
int valency;
double mass;
};
Note
The mass and sequence number cannot be negative, so it would be more efficient to use the
unsigned short intdata type.
Now, we can “create” a chemical element:
The code will look like this:
#include "stdio.h"
struct chemicalElement
{
char name[3];
int atomicNumber;
int valency;
double mass;
};
int main()
{
struct chemicalElement silicon = {"Si", 14, 4, 28.08};
return 0;
}
Access to struct fields will be discussed in the next chapter.
Try to describe the geometric point A with a structure.
Swipe to start coding
You are creating a structure to represent a point in a 2D space. Your goal is to store and display information about the point, including its name and coordinates.
The structure Point should contain:
- A character array for the point’s name — it must contain only one letter (for example, "A" or "B").
To store this single letter and the null terminator
\0, declare the array asname[2]. - Two integer fields representing the
xandycoordinates.
In the main function:
- Create a variable of type Point.
- Initialize it using curly braces {} with the name and coordinate values.
