我的程序有问题，谁能帮我改改
# includemain()
{float pi,p,K,H,L1,BFO3B,QMAX,L4,L2,L5,Y;
pi =3.1415926f;
p=pi/180;
K=1.2;
H=0.320;
L1=0.650;
BFO3B=0.25;
QMAX=180*(K-1)/(K+1)*P;
L4=H/(2*sin(QMAX/2));
L2=L1*sin(QMAX/2);
L5=L4*BFO3B;
Y=L4-L4*(1-cos(QMAX/2))/2;
printf("L1=%.4f\n L2=%.4f\n",L1,L2);
Printf("L4=%.4f\n L5=%.4f\n y=%.4f\n",L4,L5,Y);
}
亲帮我看看哪里有问题，怎么改
