        gcc -Wall -Werror -Og -o struct_array struct_array.c

    To run this program:

        ./struct_array

#include <stdio.h>

// A simple struct
typedef struct
{
    int n;
    int n2;
} simple_t; // <-- treat this as a "type" name

// Builds a struct and prints its values
int main()
{
    // Create an array to hold 4 structs of type simple_t
    simple_t arr[4];

    // Fill in the values for each struct in the array
    for (int i = 0; i < 4; i++)
    {
        arr[i].n = i;
        arr[i].n2 = i * i;
    }

    // Print out the values for each struct in the array
    for (int i = 0; i < 4; i++)
    {
        printf("The struct at index %d contains %d and %d.\n",
               i,
               arr[i].n,
               arr[i].n2);
    }
