求助大侠帮忙改一下

void *buffer2; //c变量定义必须放在开头

for(i=0;i<185;i++)
{
putimage(70+i,300,buffer1,COPY_PUT);
putimage(440-i,115+i,duffer2,COPY_PUT); //duffer2－> bduffer2,字派冲母贺粗打错了
}
for(i=0;i<100,i++) //for(i=0;i<100;i++) , ;
{
putimage(255,300-i,buffer1,COPY_PUT);
putimage(255,300-i,duffer2,COPY_PUT); //duffer2－> bduffer2,//尘拍歼duffer2－> bduffer2,字母打错了
}

closegraph():// : ;
