问题的提出：根据“心”形曲线的数学参数方程，绘制曲线并输出屏幕。在各坐标点处循环显示“LOVE”的各字母。

编程思路：“心”形曲线的数学参数方程为:





x=rsinθ/2sinθ(0<=θ<=2π)



y=rsinθ/2cosθ



用xin[2*R+1][2*R+1]存储图形。

-Of the problem: According to the " heart" -shaped mathematical curve parameter equation, drawing curves and output screen. Coordinates of points in each cycle show " LOVE"　in the letter. Programming idea: the " heart" -shaped curve of the mathematical parameters of the equation: x = rsinθ/2sinθ (0 < = θ < = 2π) y = rsinθ/2cosθ with xin [2* R+1] [2* R+1] Storage graphics.
