It should be #include .. The problem is that <> is replaces eith <> and it isn't replaced back. < is the HTML escape of < and > is the HTML escape of >. In order to prevent XSS, it may got replaced one time too much. E.g. the author wanted to use the HTML escape but the XSS protection escaped the escape and your browser undid the escape only once.

#include void main (void) { P1=0xFF; P1=0xfe; While(1) { } }这个程序是什么意思你用的是51内核的单片机，P1=0xff和0xfe都是为51单片机P1口赋值，让它输出电平罢了。后面的while(1)就是单片机进入
The first line in an 8051 C program is #include . The library file reg51.h contains the definition of all the special function registers and their bits.
1. What will be the output of following program? #include int main() { int a = 5, *b, c; b = &a; printf("%d", a * *b * a + *b); return (0); } Options: 1 ...

左移. #include<reg52.h> void Delay(unsigned int t); void main (void) { unsigned char i; Delay(50000); P0=0xfe; for(i=0;i<8;i++)
你用的是51内核的单片机，P1=0xff和0xfe都是为51单片机P1口赋值，让它输出电平罢了。后面的while(1)就是单片机进入死循环了，可以理解为单片机原地踏步，不走了。
1、点亮一个灯 # include //引用51头文件 sbit LED1 = P1 ^ 0; //位地址声明，注意：sbit 必须小写，P 大写! void main //头文件 { LED1 = 0; //点亮P1.0上的小灯} 效果图： 点亮多个灯的方法：简单来说，多sbit定义几个就行，在此不再展开。 2、闪烁一个灯
