A data structure is a group of data.

It allows you to put things together...


imagine a car that can be defined by:

struct car
{
    int number_of_doors;
    int number_of_seats;
    int number_of_mirrors;
    int number_of_brake_lights;
    int colour;
    bool solar_roof;
    bool automatic_transmission;
    string brand;
    string model;
};

Doing hat you've grouped the variables in a "set".

If you would need an array you would be able to access it like:

int j = 0;
for (int i=0,i<max;i++)>
{
  if (array_cars[1].solar_roof)
  {
    j++;
  }
}
printf("%i",j);

This is for sure not the most precise and clear explanation about structures in the world, but at least it is easy to understand.

you can define a type and then use that type as int,bool... so you could declare a new variable named whatever_you_d_like_to to represent a structure of your newly defined type.

Good luck.

Well, I think you have left it too late, but this[^] may be what you need to look at.
