错误error:  #29: expected an expression
我也在网上搜了一下，可是我√了C99也没用

单片机源程序如下:
#include "stm32f10x.h"

void delay(uint16_t z)
{
      uint16_t i,j;
      for(i=0;i<z;i++)
            for(j=0;j<110;j++);
}

int main(void)
{
      //使能时钟
      *(unsigned int *)(0X40021018)       |       =       (1<<3);
      //输出速度
      *(unsigned int *)(0X40010C00)       |       =       (1<<0);
      //输出高低电平
      while(1)
      {
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<0);
            delay(5);
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<1);
            delay(5);
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<5);
      }
}

双目运算符中间是不是不能有空格，就像双引号和两个单引号是两回事一样
