Using the following code template, define the draw_sprite function to draw a 3x4 sprite from a given (x,y) position on the terminal. It takes two integers, for x and y, and one 3x4 character array. For instance, sprite2 should be printed at (10, 9) and look like this:

^__^
(o-)
(__)

This is the code template:

#include <stdio.h>
#include <assert.h>
#include <stdbool.h>
#include <unistd.h>

struct character {
  int x;
  int y;
  int state;
  char sprite1[3][4];
  char sprite2[3][4];
};

// TODO: define the draw_sprite function here

int main(int argc, char **argv) {
  char cow1[3][4] = { { '^', '_', '_', '^' },
                    { '(', 'o', 'o', ')' },
                    { '(', '_', '_', ')' } };

  char cow2[3][4] = { { '^', '_', '_', '^' },
                    { '(', 'o', '-', ')' },
                    { '(', '_', '_', ')' } };

  struct character cow;

  cow.x = 1;
  cow.y = 1;
  cow.state = 0;
  for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 4; j++) {
      cow.sprite1[i][j] = cow1[i][j];
      cow.sprite2[i][j] = cow2[i][j];
    }
  }

  while (1) {
    printf("\x1b[2J");
    printf("\x1b[H");

    cow.x = 10;
    cow.y = 9;

    switch (cow.state) {
    case 0:
      draw_sprite(cow.x, cow.y, cow.sprite1);
      break;
    case 1:
      draw_sprite(cow.x, cow.y, cow.sprite2);
      break;
    default:
      assert(false);
    }

    cow.state = (cow.state + 1) % 2;
    usleep(500 * 1000);
  }
}
