Below is a small program that roughly represents a robot in a room. The room is defined in a two-dimensional array of characters. Objects in the room are stored as characters in the array named room that represents the room. For example, the location of the robot is stored as an R in the array. The walls of the room are stored in the array as a - for the top and bottom walls and as | for the side walls.

#include // include the curses library using namespace std; const int MAXX = 40; // maximum size of the room const int MAXY = 20; void setup(char[][MAXY], int x, int y); // room setup void print(char[][MAXY]); int main() { char c WINDOW* wnd; char room[MAXX][MAXY]; // stores the room int x = MAXX/2, y = MAXY/2; // robots initial location wnd = initscr(); // use curses to initialize the window clear(); // use curses to clear the window refresh(); // use curses to reprint the window setup(room,x,y); // setup the room with the robot print(room); // write this function!! 2 while ((c = getch()) != q) // will pause until user presses q ; // on the keyboard endwin(); // frees the screen for normal use } /* Sets up the room, adding walls, and the robot */ void setup(char r[][MAXY], int x, int y) { for(int i = 0; i < MAXX; i++) { for(int j = 0; j < MAXY; j++) { r[i][j] = ; // empty the room } } for(int i = 0; i < MAXY; i++) { r[0][i] = |; // left wall r[MAXX-1][i] = |; // right wall } for(int i = 0; i < MAXX; i++) { r[i][0] = -; // top wall r[i][MAXY-1] = -; // bottom wall } r[x][y] = R; // place the robot }

The function named setup() stores all of the initial characters into the 2 dimensional array that represents the room. For this lab your task is to build the function named print() that prints the room to the computer screen. You will need to use the curses library to write your function that prints the room. A reference for the curses library appears on the course website. Your print() function should take the room array as an argument and should loop through the entire room array, moving to the correct location on the screen and printing the character stored in the array that is to appear in the room at that location. Look at the syntax of the setup() function to determine how to pass the room array into your print() function. Please read the curses reference carefully, because you will need to use functions contained in the curses library to accomplish your goal. For example, your print() function should move to location (r,c) and print the [r][c]th element of the array for each r and c within the dimensions of the room. If you have questions regarding the use of the curses library, you should ask your instructor, or execute the command man ncurses on wormulon to read the manual for the curses library. To complete this lab you must do the following: Copy the program shown above into a file named lab8.cpp. Create your function named print to print the room as described above and add it to the program. Test your program to ensure that it functions correctly.
