A treasure is hidden someplace – the treasures coordinates are (x1, y1)! The coordinates (x1,y1) are determined randomly, using the code that is listed at the end of this exercise. The purpose of the game is for the Explorer to find the Treasure!
The explorer is allowed to go North, South, West or East, and can decide how many steps to take at once. The Explorer is first positioned at location (15,15). If the explorer goes North by one step, only the Explorer’s y coordinate is increased by 1. Similarly, if the explorer goes South by two steps, the y coordinate is decreased by 2. In the same fashion the x coordinate is increased or decreased by steps depending if the explorer goes East or West, respectively.
Each time the Explorer ‘moves’, the distance between the Explorer and the treasure is computed. The formula for the distance between (x,y) and (x1,y1) is distance = sqrt(static_cast((x-x1)*(x-x1)+(y-y1)*(y-y1)));
When the Explorer’s position is the same as the Treasure’s position, the Explorer found the Treasure!
Procedures
1. Ask the user to move: Please enter direction (n,s,e,w) and number of steps in that direction.
2. Update the Explorer’s coordinates.
3. Calculate and display the distance from the Explorer to the Treasure (this information will clue the Explorer to either keep going in the same direction or switch directions).
4. At the end of each loop display the Explorer’s coordinates.
5. Make sure that you print out how many moves it took (number of times the loop ran) to reach the treasure.
6. Use the starter code below, and see hints below the starter code to help with developing code

using namespace std;
int main ()
{
int x=15,y=15; // Explorer’s coordinates
int x1,y1; // Treasure’s coordinates
char direction;
double distance;
bool treasure=false;
srand(time(0)); // secretly seed the rand function !
x1=rand( ) % 30 + 1; // set X1 to random between 1 and 30
y1=rand( ) % 30 + 1; // set y1 to random between 1and 30
//write loop to find the treasure
HINT: When developing the code, print out the coordinates of the treasure to help in testing. Once the code works well, comment the print, or remove those lines.
