二个C语言例子,编译没通过.不知道错在哪里[求助]

以前都用汇编,C语言没弄过.

完全照书上的二个C语言例子,编译没通过.不知道错在哪里,请求帮助.谢谢

第一个程序：
#include<REG51.H>
#define uchar unsigned char
#define uint unsigned int
uchar code SEG7[10]={0xc0,0xf9,0xa4,
0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,}
void delay(uint k)
 {
uint i,j
for(i=0;i<k;i++){
for(j=0;j<121;j++)
{;}}
}
void main(void)
{
uchar m=0,n=0
P0=SEG7[n]
P1=SEG7[m]
delay(3000)
P0=0xff
P1=0xff
P2=0xff
   {
   uchar m=8,x=6
   P0=SEG7[n]
   P1=SEG7[m]
   P2=SEG7[x]
   delay(3000)
   P0=0xff
   P1=0xff
   P2=0xff
   }
 P0=SEG7[n]
 P1=SEG7[m]
 delay(3000)
 while(1)
}

第二个程序：

 #include<reg51.h>          /*item 1*/
  void msec(unsigned int);   /*item 2*/
  void main(  )
  {
  unsigned  char array[10]
   unsigned char i;
    while(1)                   /*item 3*/
    {
    for(i=0;i<=9;i++)          /*item 4*/
      {
      array[i]=P2=P0        /*单片机的C语言应用程序设计P89*/
      msec(100)
       }
     }
    }
 void msec(unsigned int x){
 unsigned char j;
 while ((x--)! =0){
  for(j=0,j<125;j++)
  {;}
   }
  }

等下再仔细检查下.谢谢您.
C没弄过,有些格式也不太清楚
