VC实验：图形程序设计及其应用 在屏幕上出现一个圆心沿正弦曲线轨迹移动的实心圆，而且，每隔四分之一周期，圆的填充色和圆的周边颜色都发发生了变化(颜色自己选取)，同时，圆的半径在四分之一周期之内由正弦曲线幅值的0.2倍至0.6倍线性增长 包含文档 源代码-VC experiment : graphic design and application procedures appeared on the screen in the center along a sinusoidal curve track the movement of a solid round, but every fourth cycle, the round filled with color and the color surrounding the circle has made a change (their color selection), while radius of the circle within the fourth cycle by the amplitude of the sine curve of 0.2 times to 0.6 times the linear growth of the source document contains generation Codes

：好风格应该成为一种习惯。如果你在开始写代码时就关心风格问 题，如果你花时间去审视和改进它，你将会逐渐养成一种好的编程习惯。一旦这种习惯变成 自动的东西，你的潜意识就会帮你照料许多细节问题，甚至你在工作压力下写出的代码也会 更好。-: Good style should become a habit. If you write code at the beginning when the issue of concern for style, if you take the time to examine and improve it, you will gradually develop a good programming practice. Once this habit becomes automatic things, your subconscious will help you take care of many details, and even under the pressure of your work will be better to write code.
