C下实现的五子棋（非双人对下)。

　　 光标的动态显示：采用setwritemode(1)函数，光标移动时在原位置再画一次，从而起到擦除原光标的效果。

　　 判胜负的函数设计：为仅检验落子处的横、竖、斜三方向的胜负，节省了大量编程时间，并使运行效率大大提高。

　　 游戏开始画面：本拟采用直接用程序画的方式，但效果不好。于是采用bmp图像显示方式，使开始画面更为美观。-under the C (121-under double right). Cursor dynamic display : setwritemode (1) function, cursor movements in the original painting a location, thereby erasing the original play cursor effect. - The outcome of a design function : to test the utility only the horizontal, vertical and oblique direction of the three results, save a lot of programming time, make operating efficiency has been greatly increased. The start of the game screen : to be used directly with the painting process, but the results are not satisfactory. Adopt a bmp image display mode, images began to be more attractive.
