在c语言中程序出现的有什么含义?
#include
sbit P1_7=P1^7;
unsigned char code table1[]={0x06,0x5b,0x4f,0x66,0x6d};

{
while(1)
{
temp=0xfe;
for(i=0;i0;a--)
for(b=248;b>0;b--);
}
}
}
源程序是这个,其中的“temp=0xfe”什么意思?

带前缀o的代表八进制,带前缀ox的代表十六进制.temp(temporary 临时的)是变量名,把0xfe赋给它,以二进制为 11111110.

C语言 extra_b1&=0xfe 这个语句怎么理解,&=这个符号代表什么? c语言的 temp=temp^0x0f是什么意思. C语言程序中“X+=3”什么意思啊? C语言中 d[3-j]=temp%10 的意思是什么 您好,老师void main() { a=0xfe; while(1) { P1=a; delay(900); a=_crol_(a,1); } }怎么接着右移呢.在这个程序中,左移完了,怎么接着右移呢单片机用C程序void main() { a=0xfe; while(1) { P1=a; delay(900); a=_crol_(a,1); } }怎 C++中“*temp”什么意思? C语言程序中temp是什么意思啊!比如#includestdio.hvoid main(){int i,j,temp,arrnum=[5]={23,9,90,250,16};.temp和arrnum=[5]={23,9,90,250,temp如何运用啊!arrnum是不是定义数组的吗! c语言 temp=0 ;0=temp的区别不好意思应该是 temp=a;a=temp P1=0xfe; temp=P1; P1= _crol_(temp,1); P1=temp; delay(10);移位函数不记的写了,谁帮我改下, %*d在C语言中什么意思 %s在C语言中什么意思 init_mx在C语言中什么意思
