Description:
- Use turbo C++ editor to write the program
- Give the path of BGI, where the BGI stored in your computer in initgraph function like initgraph(&gd,&gm,”C:\\Turboc3\\BGI”);
- Write the logic of press me gaming concept
Using functions of graphics.h in Turbo C compiler you can make graphics programs, animations, projects, and games. You can draw circles, lines, rectangles, bars and many other geometrical figures.
