How to activate the rover so that it can move itself forward, turn left or turn right in this code

1.7 Let's activate the rover so that it can move itself forward, turn left or turn right. Consider the test function below: void test 7() Mars mars; Rover curiosity; curiosity.land (mars); mars.display(); system("pause"); curiosity.turnLeft (mars); mars.display(); system ("pause"); curiosity.move (mars); mars.display(); ypwong Page 7 of 8 TCP1101 Programming Fundamentals Lab09 Trimester 2. 2018/19 system("pause"); curiosity.move (mars); mars.display(); system("pause"); curiosity.turnRight (mars); mars.display(); system ("pause"); curiosity.move (mars); mars.display(); system ("pause"); } int main() //srand( time(NULL)); //different map each time the program is run srand( 1 ); //start with seed number 1, can be any other number //test 1(); //test2(); //test3(); //test 4(); //test5(); //test6(); test(); } N18819 Your task now is to write the necessary member functions for the class Rover so that the rover can navigate itself when the commands are provided as in the test function. Take note that all those functions take Mars as the input, this is logically enough as the rover can only move when it has a surface as a reference. In another words, the rover can only move if it can sense the world as represented as a map within the Mars class. There are other simpler ways to do this if you knew pointers. 1.7 Let's activate the rover so that it can move itself forward, turn left or turn right.
