Question

我想从0显示到100 但是不知道程序中哪里错误 总是显示

#include<reg52.h>
#define uint unsigned int
#define uchar unsigned char
uchar code suzu[]={0X3F,0x06,0X5B,0X4F,0X66,0X6D,0X7D,0X07,0X7F,0X6F};
uchar temp,aa,bai,shi,ge;
sbit du=P2^6;
sbit we=P2^7;
void delay (uint z);
void display(uchar bai,uchar shi,uchar ge);
void init ();
void main ()
{
init();
while(1)
{
if(aa==20)
{
aa=0;
temp++;
if (temp=100)
{
temp=0;
}
bai=temp/100;
shi=temp%100/10;
ge=temp%10;
}
display (bai,shi,ge);
}
}

void delay (uint z)
{
uint x,y;
for(x=z;x>0;x--)
for(y=110;y>0;y--);
}

void init ()
{
temp=0;
TMOD=0x01;
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
EA=1;
ET0=1;
TR0=1;
}

void timer0() interrupt 1
{
TH0=(65536-50000)/256;
TL0=(65536-50000)%256;
aa++;
}
void display(uchar bai, uchar shi,uchar ge )
{
we=0;
P0=0xff;
we=1;
we=0;

du=0;
P0=suzu[bai];
du=1;
du=0;

we=0;
P0=0xfe;
we=1;
we=0;
delay(5);

we=0;
P0=0xff;
we=1;
we=0;

du=0;
P0=suzu[shi];
du=1;
du=0;

we=0;
P0=0xfd;
we=1;
we=0;
delay(5);

we=0;
P0=0xff;
we=1;
we=0;

du=0;
P0=suzu[ge];
du=1;
du=0;

we=0;
P0=0xfb;
we=1;
we=0;
delay(5);
}
程序哪里不对 求解答 谢谢！

Answer 1

void main ()
{
init();
while(1)
{
if(aa==20)
{
aa=0;
temp++;
if (temp==101)//原来为= ，应改为==  ,原来100要改为101，否则值能显示到99
{
temp=0;
}
   bai=temp/100;
   shi=temp%100/10;
   ge=temp%10;  
}
display (bai,shi,ge);
}
}

其他的不用改。
