关于单片机的编程问题，高悬赏求大神！！！！！

#include
sbit lamp=P2^0;
sbit kon=P3^4;
unsigned char cnt;
void delay40us(unsigned int time)
{
unsigned char ks;
while(time !=0)
{
for(ks=0;ks<10;ks++)
{ }
time--;
}
}
main()
{
cnt=0;
lamp=0; //开机先灭灯
while(1)
{
if(kon==0)
{
lamp=1; //亮灯
while(kon==0);
delay40us(50);
cnt++;
}
if(cnt==1)
{
lamp=0; //灭灯
}
}
}

#include
sbit key1=P3^4;
sbit led=P1^0;
void delayms(unsigned int t)

{
unsigned int i;
unsigned char j;
for(i=0;ifor(j=0;j<120;j++);
}
void main(void)
{
while(1)
{
if (key1==0)
{
delayms(10);
if (key1==0) led=!led;
while(key1==0);
}
}
}
