Вивчайте Creating Your First Struct

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

main.c


              1234567
            
struct chemicalElement
{
	char name[3];
	int atomicNum;
	int valency;
	double mass;
};

Note

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

Now, you can create a chemical element. The code will look like this:

main.c


              123456789101112131415
            
#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.

Завдання

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 as name[2].
Two integer fields representing the x and y coordinates.

In the main function:

Create a variable of type Point.
Initialize it using curly braces {} with the name and coordinate values.
