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 int data 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.

Tehtävä

Swipe to start coding

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