谁能帮我改一下我的C语言程序。急用！

这是我做的绘制齿轮的程序，有点问题。谁改出来就可以得到我分数了。应该不是很难的。我要可以调试出来的才可以哦。
void line(float a, float b, float c ,float d);
void featurea(float X, float Y, float D, float C1, float C2, float M, float Z,float B ,float T)

X2 = X + B/2 - C1;
X3 = X - B/2;
X4 = X + B/2;
X11 = X - B/2 + C2;
X12 = X + B/2 - C2;
Y1 = Y +(M*Z/2)+ M;
Y3 = Y +(M*Z/2)- C1;
Y5 = Y +( M*Z/2 )- 1.25*M;
Y7 = Y + T+ D;
Y9 = Y + D + C2;
Y11 = Y + D;
Y13 = Y - D;
Y15 = Y-D-C2;
Y17 = Y - M*Z/2 + 1.25*M;
Y19 = Y-M*Z/2-M+C1;

不管许多，随意添加程序，或者给个程序给我，只要且只有可以运行出画直线结果的人才行啊
