Moving car program in C++

Moving car program in C++

Moving Car Program in C++ This program is written in C++ using graphics to create and move a car. A car is made using two rectangles and two circles which act as tyres of car. A for loop is used to move the car forward by changing the rectangle and circle coordinates and erasing the previous contents on screen using clearviewport, you can also use cleardevice. Speed of car can be adjusted using…
